Grand Canyon of the Tuolumne

Overview

A granite trench carved by the Tuolumne River, this 29–33 mile point‑to‑point backpack links White Wolf and Tuolumne Meadows through a canyon roughly 3,000 feet deep. Expect near‑constant river views, polished slabs, and a marquee string of waterfalls—California, LeConte, and Waterwheel—plus clear pools that make the heat bearable in late summer.

Route & Direction

You can hike it either way:

• White Wolf → Tuolumne Meadows: Very steep initial descent to Pate Valley, then a steady upstream climb as scenery generally improves toward the falls and Glen Aulin.
• Tuolumne Meadows → White Wolf: A gentler downhill along the waterfalls first, saving the stout climb out of Pate Valley for the end when your pack is lighter.

Either direction, plan for a hot, sustained effort near Pate Valley and start big days early.

Permits & Regulations

A Yosemite wilderness permit is required. 60% of quota opens 24 weeks in advance; the remainder is released closer to the trip. Fees apply, and permits are picked up at a permit station. A bear canister is required for all food and scented items; hanging food is illegal, and bear spray is not allowed. Your entry trailhead determines where you can camp on night one (for example, Glen Aulin entry versus pass‑through options).

Logistics & Transportation

Because it’s a one‑way route, most hikers run a two‑car shuttle. Seasonal options include the hikers’ bus between the Valley and Tuolumne Meadows and YARTS service when Tioga Road is open. Hitchhiking is legal in the park, but use judgment. On the Tuolumne side, parking near Lembert Dome is commonly used; White Wolf has a small lot (when the road is open).

Water, Camps, and On‑Trail Realities

You’ll often be near the Tuolumne River, but there are meaningful dry stretches—top off at flowing side creeks like Morrison Creek and be ready for sections where the trail leaves the river between Pate Valley and Muir Gorge. Camping is dispersed (no facilities) with popular zones near Pate Valley, along the river east of Pate, and around the big waterfall corridor; avoid camping within a mile of Glen Aulin High Sierra Camp. Expect no toilets or taps—treat all water and follow Leave No Trace.

Hazards & Wildlife

Heat is the headline challenge, especially in Pate Valley. Rattlesnakes are more common at lower elevations. Granite near the falls can be slick; swim only where currents are calm and never above waterfalls. Early season may bring blowdowns, cold fords if bridges are out, and lingering snow higher up.

Best Time to Visit

• Late spring to early summer: Biggest, most dramatic waterfall flows, but expect colder water, potential for icy fords, and lingering high‑country snow.
• Late summer to mid‑September: Warmer swimming, typically easier permits and transport, and safer crossings, but lower flows and hotter conditions down low.

Backpacker Extras

Backpackers’ campgrounds (e.g., White Wolf or Tuolumne Meadows) are available the night before/after your trip for a small per‑person fee; overnight parking belongs in designated trailhead areas.
