Charlotte Lake

Quiet alpine lake with campsites, bear boxes, and big-sky views

InsideKings Canyon National Park

Overview

Charlotte Lake is a classic High Sierra basin: turquoise water, granite walls, and big-sky sunsets. It’s quieter than nearby Kearsarge Lakes and makes a superb basecamp for backpackers—close to the JMT/PCT corridor and just a couple miles from Glen Pass. Expect cold, clear water that’s perfect for a quick dip if you’re brave.

Getting There

Most hikers reach Charlotte Lake from the east via Onion Valley over Kearsarge Pass, then descend past the Kearsarge/Bullfrog basin to a short spur for the lake. Plan for a full, strenuous day with significant elevation gain to the pass and a downhill finish into the basin. A challenging there-and-back day from Onion Valley is roughly 17–18 miles with around 4,500 feet of gain. From the west, you can also come up Bubbs Creek from Road’s End to the JMT and cut over, but that’s a longer, multi-day option.

Camping and On-Site Notes

Charlotte Lake has established backcountry campsites, bear boxes, and a ranger station in season. It’s typically a quieter scene than the more popular basins just east of the pass. Follow backcountry rules: camp set back from water, use the bear boxes properly, and keep the area clean.

Wildlife and Safety

This corridor is known for very active black bears—store all food and scented items correctly and stay vigilant around camp. Deer and marmots are commonly seen. Avoid contact with bats or any wildlife behaving oddly, and report concerns to rangers. Mosquitoes can spike near water in the evenings, especially mid-summer.

Trail Conditions and Season

High country travel here is usually best from late June through October, when passes tend to be snow-free. Earlier or later, expect lingering snow and ice. Water is plentiful but always filter. Afternoon winds can kick up near the pass and the lake.

Best Time to Visit

Season: Late June–October is the sweet spot for clear trails and open passes.
Day of week: Weekdays see fewer backpackers than weekends.
Time of day: Start the pass early for cooler temps and calmer winds; mornings bring glassy reflections on the lake and gentle light for photos.

Who Will Love It

Backpackers looking for a serene, well-situated camp near the JMT/PCT, photographers chasing alpine light, and strong hikers who don’t mind a big climb to reach a quieter corner of the high country.

Pros

Scenic alpine basin near the JMT/PCT and close to Glen Pass

Cons

Strenuous, high-altitude approach over Kearsarge Pass or via Bubbs Creek
Active bears and seasonal mosquitoes near water

Tips

Start by sunrise to beat heat and wind on Kearsarge Pass.
Carry a bear canister and use the lake’s bear boxes for redundancy.
Filter all water; sources are plentiful but must be treated.
Expect mosquitoes at dusk near water in mid-summer; bring repellent or a headnet.
If coming from sea level, spend a night at elevation to acclimatize before the pass.
