I was in the mood for a climb, this out and back hike is just shy of 8 miles and climbs to the peak of Black Mountain from the bottom of the foothills, ascending 2,100 feet. Expansive views over the green ridges of the preserve and Silicon Valley below reward the climb.
Rancho San Antonio is a very popular park and the main entrance has multiple parking lots, but there’s a smaller “back” entrance at Rhus Ridge Trailhead, a smallish parking lot that also filled up quickly on the weekend I went.
Nestled at the base of the hills the trail follows a dirt road, immediately climbing quite steeply. The steepness, though, rewards with views over Silicon Valley. At first, the dish, perched on top of the Stanford foothills, is visible in the distance, and the vista continues to widen to present the peninsula from Palo Alto to Mountain View.
As Rhus Ridge Trail tops out at the top of, well, what I assume is Rhus Ridge, the views behind vanish and the park opens up in front, the rolling green ridges and valleys, Black Mountain shrouded in mist in the distance, as the clouds start to open up to blue skies overhead. From here Black Mountain Trail continues the climb.
Black Mountain Trail is a single track trail that gently slopes, contouring the ridges, switchbacking up and up. Views open up across the park and over towards Cupertino. I’ve never actually seen Apple’s spaceship campus, and at first I couldn’t figure out what the giant circle next to highway 280 was.
Black Mountain Trail meanders through wooded oak, eventually opening out to the gentle humming of a power transmission tower, and turns into a dirt track, presumably built to service the power lines (a short way up the trail branches to a the recently renamed to Stephen E. Abbors Trail, previously called the PG&E Trail).
The track climbs the final span to the edge of the preserve, just short of Black Mountain, more steeply now. Both times I’ve been to Black Mountain from Rancho San Antonio the peak disappears into the mist, the heat from the sun replaced by a cold wet wind blowing over the ridgeline. It’s not always so, I visited from the Monte Bello side under blue skies.
Rancho San Antonio ends at a radio tower installation, and shortly past is the flat peak of Black Mountain in Monte Bello Open Space Preserve. I walked up to the summit, but the wind was blowing, my hair was wet, and nothing was visible through the thick mist. I didn’t linger long before turning around and retracing my steps. Before long the mist is gone again and the clouds have parted to the blue skies of California.
A great trail for views across south Silicon Valley and hill climbing, although be warned it’s scorching hot in the summer, early mornings are best.
Sierra Azul Open Space Preserve is a rugged and steep park on the edge of Santa Cruz mountains. The trail system is mostly old fire roads which were not designed for hikers and are persistently steep, but partly it comes with the terrain.
The trail system is actually pretty extensive, especially now that the trail to Mount Umunhum has opened, but you have to be a glutton for hill climbing to do any very long hikes.
Kennedy Trail starts at the base of the mountains near Los Gatos and follows a fire road as it climbs up to reach Mount El Sombroso. It’s mostly surrounded by people height brush, but due to its steep dry slopes there aren’t many tall trees so views over the valley open up.
The lack of overgrowth also means limited shade, and in the summer the trail is hot. So hot that, along with the usual mountain lions, ticks, and rattlesnakes, the trail signage has warnings about signs of dog dehydration for dog walkers.
The trail is popular with dog walkers, mountain bikers, trail runners, and hikers alike, and is despite its heat and steep slopes, or maybe because of those steep slopes, on a weekend you’ll likely to see all of the above.
When I arrived at the trail junction, my turn around point for a total hike of just under 8 miles with 2,000 feet of elevation change, I was greeted with the fog rolling in from the Pacific and burning off as it hugged the crest of the Santa Cruz mountains. I guess that’s why this end of range is so hot and dry and the other side of the range is lush redwood groves.
An 8 mile loop in Windy Hill Open Space Preserve starting at the base of the Santa Cruz Mountains and climbing up to the top and back down again. The undergrowth and hills are glowing green following the winter and early spring rains.
It’s springtime in the bay area and the temperatures are starting to climb, the skies are turning blue, memories of rain are receding, and the foothills are flush with green. In a few months they’ll be scorching hot and golden brown as the moisture evaporates into dust.
I have had a late start to the hiking season this year, not getting out until this past weekend for the first time. I’m hoping to spend a lot more time backpacking in the Sierras again this summer. I kicked off the season with a gentle 8 mile loop in the Windy Hill Open Space Preserve.
The trailhead I started from is at the last intersection of Alpine Road, which is also a trailhead for Coal Mine Ridge trail system. On the weekends the Santa Cruz mountains are teaming with lycra clad cyclists, both cycling and hiking are very popular in the Bay Area, and for good reason. A steady stream of cyclists zips past climbing up Alpine Road.
The loop I did takes a connector trail to Hamms Gulch Trail and then follows to Eagle Trail. Hamms Gulch is a very popular trail but I’ve taken Eagle Trail to Razorback Ridge Trail twice now and both times its been much quieter, usually only seeing a couple of trail runners.
Eagle Trail follows alongside Alpine Road, but at this point Alpine Road has turned into a dead-end so there’s no traffic on it, save for the cyclists. The trail connects back to the road in a couple of places to cross bridges before branching away and turning into Razorback Ridge.
Razorback Ridge zig zags up the side of the mountain. It’s a very well-built trail and is a very gentle climb up to the top of the ridge. The whole loop is shaded, even early on a spring morning the exposed sun would heat you up so the shade is welcome. As the trail nears the top of the ridge, stopping just short of Skyline Road, some views across the preserve and bay open up. The sound of motorcycles whining along Skyline grows.
Razorback Ridge becomes Lost Trail and continues to zig zag, this time contouring the ridge. This early in the year there are little streams down some of the gullies, and this early in the morning the ground is wet from the morning mist. Along the way I passed two Open Space Preserve rangers cutting a tree out of the trail.
Lost Trail meets with Hamms Gulch, and continues on to the exposed windy hills for which the preserve gets its name (which this morning were not windy at all, although last time I was here were very windy). I take the branch and follow Hamms Gulch down to close the loop. Hamms Gulch is a much busier trail, and maybe it’s also just a little later in the day.
All in all this is a pretty springtime hike, and thanks to the mostly shaded route I imagine would be pleasant in the summertime too, especially early in the morning. From the top there are glimpses across the bay from Palo Alto up to San Mateo. My first hike of the season under my belt I’m looking forward to more to come.
An easy off trail hike to Hetch Hetchy Dome, overlooking Wapama Falls, exploring Falls Creek basin, and to Condon peak, towering over Hetch Hetchy Reservoir.
As the temperatures cool off in fall I headed to Hetch Hetchy for the weekend. Hetch Hetchy sits relatively low in the Sierra and gets very hot in the summer months. It was also the peak of the Orionids meteor shower in the early hours of Sunday morning so under clear skies I hiked into the wilderness.
I did the Lake Vernon loop in the spring so this time I was looking for a different route that’s doable in a weekend. Scouting the maps for a destination Hetch Hetchy Dome on the north rim of the valley looked like it had a large flat top, is accessible with an off trail hike from the top of the switchbacks, and looked like it would offer great views over the reservoir.
I checked in with the ranger while picking up my permit, and he remembered me from my trip earlier in the year. He said I should have no trouble getting over to the Falls Creek basin, which feeds Wapama Falls. He recommended going to the top of the granite cliff to the west of the falls and peering over and assured me that I would have the entire basin to myself.
The parking lot is on the south side of the dam and the trail immediately starts by traversing over the dam and through a walkway blasted through the granite. I couldn’t help myself from taking the same set of photos while crossing over the dam. The water level didn’t seem to be any different to the spring time, a testament to how much water was in the snowpack this year. At the highest elevations not all the snow melted and won’t now as the overnight temperatures routinely drop below freezing.
The trail follows a short way around before switchbacking up over 1,500 feet of vertical. At the last switchback the reservoir is hidden from view and the trail starts to head into the forest. Just past the top there’s a trail junction with a fire road to Miguel Meadow and Lake Eleanor. I take the trail towards Beehive and follow it for a short distance before turning right to follow the north rim of the valley off trail.
The forest is pretty open at this elevation and it’s easy to follow around. I stick at around 5,400 feet elevation and follow the contour. There are many game trails through the brush that make it easy-going. There are rock outcroppings here and there which offer views down to the reservoir. At this time of year Tueeulala Falls is dry, but it’s pretty easy to tell which creek would have fed it as I climb over.
I reach the smooth granite dome at the top of the vertical cliffs besides Wapama Falls at lunch time and lay out on the warm granite to eat my sandwiches. The views from here are really stunning, you’re just across from Kolana Rock, at about the same height, right where the valley bends around the rock, and the sheer cliffs just below offer a view up and down the reservoir as well as to directly below. I’m definitely a little timid when it comes to getting to the edge of such a sheer drop but the top was large and flat and I had a pretty good view without going right to the edge.
After lunch I skirted around the edge of the cliff to drop down to the top of the falls. The cliff edge here was vertigo inducing. The top of Falls Creek was actually really beautiful, there’s a little pool right before the edge with sandy banks. I imagine in the heat of summer it would be amazing to swim in, so long as you stay away from the edge!
But I had my eyes set on Hetch Hetchy Dome so I jumped some stones over the river and headed up the granite ledges on the other side. Getting up to the dome was the steepest part of the day, another 800 feet of climbing, and by the time the granite started flattening out I was starting to get low on energy as the sun beat down. I headed over to the dome peak. Because the dome is so large and flat on top the peak doesn’t actually offer direct views of reservoir, you have to walk down a little. Right past the peak there’s a set of eye bolts set into the granite, apparently during World War 2 there were cables strung between Kolana Rock and Hetch Hetchy Dome as an anti-aircraft measure.
I had eyed up heading up-stream to explore the pools along Falls Creek but I decided to have an easier afternoon and scout out a campsite on back down on the west side of the creek. Finding a campsite in the basin was easy, the granite on the west of creek rises pretty gently and there’s a lot of flat ridges to choose from. I selected a site, put up my tent, inflated my mattress, and lay down in the late afternoon sun in the golden grasses.
Early Sunday morning was scheduled to be the peak of Orionids meteor shower. The Orionids are residue from Halley’s comet as it rotates the sun and the earth passes through its path. They’re named as they appear around the Orion constellation in the night sky. As the sun set the moon was visible low in the sky, it was only 3 days since the new moon and it setting just an hour or two after the sun. As it disappeared into the faint yellow glow of the sun the sky was illuminated by the milky way.
I crawled into my tent as the wind picked up slightly and was causing a chill lying outside. I saw a couple of shooting stars but my eyes were feeling heavy so I decided instead to poke my head out of the tent in the early hours when it was meant to be the best viewing time when I inevitably woke up in the night. Sure enough, as I checked my watch, 3am rolled around and I opened up my door and lay my head outside. By this time the milky way had disappeared and Orion was clearly visible in its place. I trained my eyes on the sky and watched out. I saw a few more shooting stars but my eyes were still feeling heavy, so I called it good and closed my eyes until the morning.
As the night sky made way to dawn I had my morning coffee and packed down my tent. The hike back was retracing my steps from the previous day, contouring back around trained on 5,400 feet. The landscape in the morning light is magical, the sun rose over the reservoir and peeked through the trees.
Instead of heading straight back down I took a small detour right before the switchbacks. When I got to the trail I crossed straight over and headed up to Condon Peak. It’s right at the top of one of the granite ridges that the O’Shaughnessy Dam rests on, to the north. The slopes leading up to the domed peak were fairly steep and covered in brush which required a little bushwhacking, scratching up my arms and legs in the process. But it wasn’t too far and it was well worth it for the view from the top. Looking down to the valley below I couldn’t help but wonder if John Muir had looked down on green meadows from this point and felt a little heartache that the dam had been built at all.
The weekend was really a lot of fun. I think it would be a great day hike to reach the cliffs above Wapama Falls. While Hetch Hetchy Dome sounds a little magical, after all Yosemite is famous for its granite domes, I think it might actually have been more fun to explore the Falls Creek basin. Condon Peak was also well worth the detour and could also be done as a day hike, taking the whole day and going to the top of Wapama Falls and Condon Peak would offer views over the reservoir that few see.
The views from the top of Granite Dome look out across the entire Emigrant Wilderness and there are many pristine mountain lakes nestled in the expansive and gently sloping granite slopes, polished smooth by glaciers.
Two weeks after my last trip to Emigrant Wilderness I went back for another overnight backpacking trip, this time with Granite Dome in my sights. My last trip there was a blanket of snow over the mountains but in the time since almost all of it had melted, only remaining in shady or north facing slopes at high elevations.
I started out from Kennedy Meadows Trailhead, bright and early, after a cool motorcycle ride in. This time I had heated socks, and, other than that my right sock came unplugged when I threw my leg over the bike at the last fill-up, they worked a treat. I made breakfast and a cup of coffee at the trailhead, and set out.
On the way past Relief Reservoir I took a small detour to venture down to the dam itself. There’s even more rusted out machinery scattered all over as you get nearer to the dam, and what looks like the entrance to a mine as a concrete doorway leads into the granite. I couldn’t tell whether there was an official trail to the dam but it wasn’t too hard to get to. There’s a walkway all along the backside of the dam and you can get to the other side, but I only went to the middle. From the dam you can see right across the reservoir and to Granite Dome behind it.
From the dam the trail follows around the reservoir, first dropping down to cross the Grouse Creek drainage, and then climbing up to a fork, one way leading up Relief Valley and the other towards Lunch Meadow. From here there’s probably many different options for climbing up to the lakes below Granite Dome, but I chose to follow the trail up to Lower Relief Valley and follow the drainage up from there.
Lower Relief Valley is a large meadow, encircled by granite. After grabbing lunch I left the trail and skirted around to the creek on the opposite side. The creek cuts down layers of gently sloping granite, draining from Ridge Lake and Iceland Lake 1,200 feet above. The walk up is easy to navigate but it’s a straight walk up and the elevation gain was starting to take its toll on my energy level. When I finally crested the drainage and gazed over Ridge Lake I was ready for a break, and I couldn’t have asked for a prettier place to take one.
Nestled in the folded granite on the north side of Granite Dome there’s a number of pristine mountain lakes and views down to the valleys below. I walked from subpeak to subpeak, taking in Ridge Lake, Iceland Lake, Sardella Lake, Lewis Lakes, and smaller unnamed bodies of water. The huge granite ridge climbs up behind, the north slope still blanketed in a layer of snow. For the most part the granite is huge, smooth, and gently sloping, with a few boulder fields near to the cliffs below the ridge.
The walk up to the top of the ridge is pretty easy, I walked around to Lewis Lakes and curved up through a permanent snow field to the top of the ridge, which is large and flat. The wind was much stronger on top, and freezing cold. The peak isn’t very prominent on the ridge and the views are fantastic all along, although as it’s so flat you don’t get to take in the entirety of both sides at once.
To the south you can see far into the distance, across Emigrant Wilderness and towards the peaks in Yosemite, Long Lake with its little islands is prominent in the valley below. To the north you can see the lakes directly below the ridge and further down to Relief Reservoir. I had been considering camping on the ridge but the wind was too strong so I instead headed back down to camp below the north ridge.
I had the entire set of lakes all to myself. Overnight the wind died down and by morning the air was completely still. The moon was a couple of days off full and I got up pre-drawn to watch the light change and sun rise over the lakes. Morning is my favorite time backpacking, the smell of coffee brewing and the warm cup heating cold hands, the darkness of night fading through deep blue, then orange and yellow, the heat of the first rays of sun as it crests the surrounding mountains, and the anticipation of the day ahead.
After eating breakfast, watching the sun rise, and breaking down camp, I spent a little time walking around the lakes, seeing them again in morning light, before following the drainage of Ridge Lake back down to the valley below. I decided to just retrace my steps back down to the trailhead instead of seeking out a different route.
On the hike out I stopped at Relief Reservoir for lunch and there was a helicopter landed down near the reservoir. I couldn’t see any people and it didn’t look like a SAR helicopter. I also saw multiple groups of horses and pack animals. Right now is hunting season and it seems like the hunters like to use pack animals to come into the wilderness, but I’m guessing that there are horses coming out Kennedy Meadows Resort throughout the peak season.
Granite Dome was an amazing weekend destination, but it was pretty enough that I could easily have spent a few days in the vicinity. It would also be amazing to see in the early season with frozen lakes.
