Glen Aulin

Overview

Glen Aulin is where the Tuolumne River drops through a polished granite canyon in a string of cascades and falls—Tuolumne Falls and White Cascade first, then farther down to California, LeConte, and Waterwheel. It’s classic High Sierra: luminous meadows, glacier-smoothed stone, and cold, clear water. John Muir called it “the most spacious and delightful high pleasure-ground I have yet seen,” and on a calm summer morning you’ll see why.

The Hike & What You’ll See

Most hikers start near Tuolumne Meadows (Dog Lake/Lembert Dome area) and follow a well-signed path along the river. Expect roughly 10–13 miles round-trip to the Glen Aulin area with about 800–1,200 feet of gain—moderate overall, with the steeper work on the way back out. The approach is gentle through meadow and forest; stone steps lead down toward the canyon, the backpacker camp, and White Cascade. If you’ve got gas in the tank, continue downstream for bigger, wilder waterfalls—just remember every step down is one you’ll climb back.

Camping, Permits, and 2025 Camp Status

Day hikes require no permit. For overnight trips, you’ll need a Yosemite wilderness permit and a bear-resistant canister for all food and scented items. The backpacker area at Glen Aulin sits near Conness Creek and typically offers bear boxes and pit toilets; there’s no cell service. In 2025, the Glen Aulin High Sierra Camp is not operating (no meals, no tent-cabins, and utilities like potable water and toilets aren’t available to rely on), so plan to be fully self-supported and treat all water.

Season, Conditions, and Hazards

Tioga Road must be open to reach the trailhead—generally late spring to fall. Mid to late summer brings safer river levels and peak wildflowers, though afternoon thunderstorms are common. The Tuolumne can be swift and frigid; keep a generous buffer from cascades and avoid risky creek crossings. Summer bugs can be relentless; strong repellent and sun protection are your friends. Wildlife sightings are common (deer, and occasionally black bears). Store food properly and give bears space.

Amenities and Logistics

You’ll find pit/vault toilets at the Dog Lake/Lembert Dome trailhead, near Parsons Lodge, and at the Glen Aulin backpacker area. Day-use parking and food-storage lockers are available at the Dog Lake/Lembert Dome lots. There’s no parking at Glen Aulin itself—it’s a hike-in destination—and coverage is spotty to nonexistent.

Photography and Vibe

Early light glows across granite slabs and meadows; sunrise and sunset can be sublime around the canyon rim and cascades. The sound of water is constant, the crowds thinner than the Valley, and the whole place invites lingering.

Best Time to Visit

• Time of year: Mid–late summer for wildflowers, clearer trails, and more manageable river levels.
• Time of day: Start early for cooler temps, easy parking, and mellow crowds; storms often build in the afternoon.
• Days of week: Weekdays are quieter during peak season.
• Light: Soft morning and evening light flatter the canyon and falls; mid-day glare can be harsh on the granite.
