Trail Report: Onion Valley to Kearsarge Pass

Kearsarge Pass Hike // tahoefabulous.com

This weekend I set my feet on my highest ever point: 11,760 at Kearsarge Pass in Kings Canyon National Park.

The Kearsarge Pass trail is a popular re-supply route for Pacific Crest Trail and John Muir Trail through hikers. The trail wanders uphill through the John Muir Wilderness on the way to Kings Canyon National Park with sweeping vistas of the high Sierra in every direction. The trailhead begins at the Onion Valley campground about 15 miles outside of Independence, California in the Eastern Sierra. To get to Onion Valley Campground, head towards Independence (about 42 miles south of Bishop) on Highway 395. Once in Independence, turn onto West Market Street, which quickly turns into Onion Valley Road. There are several campgrounds along Onion Valley Road or you could stay in Independence, as there is non-campground parking near the trailhead. We stayed in one of the walk-in camping spots at Onion Valley Campground, which makes for an easy and convenient early start. Note: Onion Valley Campground is high (above 9,000 feet!) – so pack accordingly. You’ll want more warm layers than the temperature in much lower, hotter Independence seems to indicate.

The entire Kearsage Pass trail is a steady climb from about 9,200 feet up to a maximum of 11,760 feet at the top of Kearsarge Pass over 4.8 miles. While the trail is never extremely steep, be aware that you are at high elevation. The going is much more difficult than a steeper, lower elevation climb. I live at 6,200 feet and I was really feeling the difficulty when I got about 10,500. Be prepared to go more slowly and take lots of breaks, especially if you are new to high elevation hiking. We hiked the 4.8 miles and climbed just over 2,500 feet with a moving time of 2:05:40, however our elapsed time was 3:20:20 which means we took nearly 1:15 in breaks across the nearly 5 miles.

Kearsarge Pass trail closely passes several gorgeous alpine lakes, with Flower and Gilbert Lakes close enough for a refreshing dip or quick fishing pit stop. Warning: these lakes can be extremely mosquito-y! We were chased off before doing more than dipping our toes in, but there were a number of other hikers and fishermen that braved the swarms (probably armed with bug spray). The stunning views of the hike begin almost immediately, and we were frequently stopping to admire the vistas and take pictures.

The whole trail is incredibly well built and maintained. There aren’t too many tripping hazards and the switchbacks are gradual, allowing you to soak in your surroundings and concentrate less on your feet. The rocks surrounding the trail and making up the nearby peaks are interesting enough to catch the eye of the geology inclined in your group. You’ll see a bunch of California’s state rock, serpentine (hint: it’s the greasy looking, greenish one). I’d also recommend bringing along a field guide with a good wildflower section (like the Laws Field Guide to the Sierra Nevada or Wildflowers of California). We saw at least a dozen different varieties of wildflowers during our hike.

The trail climbs at a fairly steady 500 feet per mile, and I started really feeling the exertion of hiking at high altitude at about 2.5 miles and 10,500 feet. Luckily, the gorgeous views help distract from the hard work.

At about 4 miles, you’ll come to your last couple switch backs and the end is in sight! You might see people up at the top of the pass that seem very far away, but the final push wasn’t as bad as I thought it was going to be. There are only a couple of switch backs, and you’ll mostly be headed straight toward your goal. The vistas are even more incredible in this section. Keep your eyes out for a very steep summit to the south that only gets more interesting as the trail climbs higher.

When you finally reach the top of Kearsarge Pass, take your time to soak in the views and rest for the trip back down. Check out these amazing views!

At the pass, you’ll enter Kings Canyon National Park, and could continue your hike onto the John Muir Trail and down to Kearsarge and Bullfrog Lakes, and even further to connect with the Pacific Crest Trail. We decided the top of Kearsarge Pass was enough of a climb for us. Unfortunately, I had a user-related Strava malfunction on our trip down, so I’m not sure how long it took. I paused Strava when we stopped to check out one of the lakes. Mosquito swarms descended, and, in the panic of our escape, I forgot to re-start it! It took us about an hour to do the first 2.4 miles, and I imagine the second half took about the same time. So we’ll say the descent took about 2 hours.

This was a difficult and rewarding hikes with some of the best views I’ve encountered in the Sierra. If you are looking for a high Sierra hike or backpacking trip (permits needed) that’s challenging but completely doable for an in-shape individual, I would highly recommend the Kearsarge Pass trail.

Trail Stats:

Length: 4.8 miles to the top, 9.6 round trip

Elevation: 2,500 feet of elevation gain

Duration: ~5:20 total, for reasonably in-shape hikers that live at 6,500 feet
