About This Permit

Big Pine Creek South Fork is an Inyo National Forest wilderness entry point above Big Pine, climbing the South Fork toward Brainard and Finger Lakes.

Inyo's quota season runs May 1 to November 1 in 2026, with reservations opening six months in advance at 7 am Pacific and additional permits released two weeks ahead. Outside that window the trailhead is non-quota with a two-week booking window.

Two things make this the harder fork. Inyo states the bridge across the South Fork Creek was destroyed by avalanche in spring 2011, so the crossing is a ford, and the trail beyond Willow Lake becomes indistinct with rock cairns marking the way. The permit does not include the North Fork.

The Experience

Why It Matters

Inyo National Forest describes the Big Pine South Fork trail to Brainard and Finger Lakes climbing beneath the Norman Clyde and Middle Palisade Glaciers with views of the jagged crest of the Middle Palisades. It is the quiet fork, and the reason is right there in the agency's own text: the bridge is gone and the trail runs out.

The Route

Inyo is direct about the crossing: the bridge across the South Fork Creek was destroyed by avalanche in spring 2011, so expect to get your feet wet and use caution with high spring runoff.

Above Willow Lake the trail becomes indistinct, with rock cairns marking the way to the upper lakes. Brainard and Finger Lakes sit beneath the Norman Clyde and Middle Palisade Glaciers.

This permit does not include the North Fork, and Inyo asks you to check the area map to select the correct trail. Campfires are prohibited, and stock is not recommended beyond Willow Lake.

The Feeling

You get wet feet early and you stay honest the rest of the way. Above Willow Lake the trail stops being a trail and becomes a line of cairns across slabs, with the Middle Palisade crest getting bigger every hour.
