Kearsage Pass

The hike to Kearsarge Pass from the Onion Valley trailhead is approximately 4.5 to 4.8 miles one-way, with an elevation gain of about 2,500 to 2,623 feet. For most hikers, a round trip typically takes 6-8 hours, depending on fitness levels and how much time is spent enjoying the views at the pass and along the lakes.

While the Kearsarge Pass Trail is incredibly scenic, it involves a significant elevation gain over a relatively short distance, making it a challenging hike. Beginners with good physical fitness can attempt it, but should be prepared for a strenuous ascent. Shorter hikes to some of the lower lakes, like Little Pothole Lake or Gilbert Lake, offer a less demanding option to experience the area's beauty.

Kearsarge Pass is primarily accessed via the Kearsarge Pass Trail from Onion Valley, which is an out-and-back route for day hikers. However, for multi-day backpackers, the pass serves as a critical entry or exit point to connect with the John Muir Trail (JMT) and Pacific Crest Trail (PCT) further west, allowing for longer loop or thru-hike itineraries within the High Sierra.

Parking is available at the Onion Valley trailhead. However, it's a very popular spot, especially during peak season (summer and early fall). Visitor tips suggest that the parking lot fills up quickly, so arriving early in the morning is highly recommended to secure a spot.

Day hiking to Kearsarge Pass typically does not require a permit. However, overnight stays in the wilderness, including backpacking beyond the pass into Kings Canyon National Park or the John Muir Wilderness, absolutely require a wilderness permit. These permits are issued by the Inyo National Forest and are highly sought after, often requiring reservations months in advance.

Yes, dogs are generally allowed on the Kearsarge Pass Trail, as it is located within the Inyo National Forest and John Muir Wilderness. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Always remember to pack out all pet waste.

The Kearsarge Pass area is home to diverse wildlife. Hikers might spot various bird species, marmots, pikas, and deer. More elusive animals like black bears and the endangered Sierra Nevada Bighorn Sheep also inhabit the region, though sightings are rare. Always maintain a safe distance and never feed wild animals.

Winter hiking to Kearsarge Pass is possible but presents significant challenges and is only recommended for experienced mountaineers with proper gear and avalanche awareness. The Onion Valley Road leading to the trailhead is typically closed from November to May due to heavy snow, requiring a much longer approach. The pass itself will be covered in deep snow and ice, necessitating snowshoes, skis, or crampons, and potentially an ice axe.

There are no facilities directly at the Kearsarge Pass trailhead or along the trail itself. The nearest amenities, including cafes, restaurants, and accommodation, can be found in the towns along Highway 395 in the Owens Valley, such as Independence, Lone Pine, or Bishop. These towns are popular resupply points for long-distance hikers coming off the pass.

The entire trail is incredibly scenic. Key viewpoints include the series of five picturesque subalpine lakes: Little Pothole Lake, Gilbert Lake, Flower Lake, Heart Lake, and Big Pothole Lake, each offering stunning reflections. From the pass itself, you'll be treated to panoramic views of the Kearsarge Lakes, the dramatic Kearsarge Pinnacles, the Kings-Kern Divide, and University Peak, with the vast Owens Valley stretching out to the east.
