Wallace Lake Trail

Overview

This is a serious, multi-day backcountry push to a striking high-alpine lake tucked beneath granite walls in the Whitney region. The route is approximately 41.7 miles total (out-and-back) with about 10,541 feet of elevation gain. You’ll begin on the Shepherd Pass Trail around 6,400 feet, grind through long switchbacks, join the Pacific Crest Trail, then turn off at roughly 11,500 feet toward Wallace Lake.

What You’ll See

As the trees thin, the landscape opens into wide, glacially carved granite—polished slabs, rolling domes, and big sky. Near the lake, expect meadows where Wallace Creek braids and slows, photogenic pools and small ponds, and a notable inlet cascade. Wallace Lake itself is a stark, beautiful bowl of blue set in pale stone. If conditions and energy allow, a short wander beyond the lake reveals views toward adjacent Wales Lake with its cliffs and little islands. Sunrises and sunsets can be dramatic here—think alpenglow on rock spires and fiery evening clouds.

Trail Experience

The approach via Shepherd Pass is steep and sustained, transitioning into exposed high-country travel with very little shade. Weather turns fast at altitude—brief showers, clearing skies, and strong wind are common. Near the lake, expect intermittent use paths and occasional “lose it, find it” moments, so basic route-finding helps. Surfaces range from sandy tread to granite slabs and rubble. In higher-flow periods, bits of trail can act like a creek, and you can encounter muddy stretches.

Camping and Water

You’ll find viable, flat, well-drained camps near Wallace Lake with some wind shelter, though overall exposure is real; some parties prefer to camp a bit lower among trees if weather looks feisty. Water is available from creeks and pools along the approach—plan to treat or filter everything.

Difficulty and Who It’s For

This is an advanced, remote, fully exposed, high-elevation route with no resupply. If you like big elevation, solitude, and classic Sierra granite, it delivers. If you’re new to backpacking or hoping for an easy lake ramble, this isn’t the place to start.

Best Time to Hike

Mid to late summer into early fall, after snow has receded, is the sweet spot. Start days early to beat afternoon buildups and to manage the fully exposed sections under cooler light. Weekdays see fewer people as you near the lake (it’s already quiet), and golden-hour light sets the surrounding granite aglow for photography.

Permits and Logistics

Overnight wilderness permits are required. This itinerary begins on the Shepherd Pass approach before entering the higher country; secure the correct permit for your starting trailhead and itinerary. There are no services or resupply along the way—pack for full self-sufficiency.
