Franklin Pass Trail

Overview

This is Mineral King’s classic high-country traverse: a demanding but rewarding 21.4-mile total out-and-back over Franklin Pass to the junction near Forester Lake. Expect a steady west-side climb from lush Rattlesnake Creek into rockier, then sandy, high-elevation terrain, with huge panoramas from the crest. It’s popular up to Franklin Lakes, then quickly quiets down beyond the cirque.

Route and highlights

Start at the Mineral King Pack Station (most people park nearby and walk down the short road). Around 3.8 miles in, pass the signed junction for Farewell Gap and continue toward Franklin Lakes. The traverse along Franklin Creek shows off colorful metamorphic slopes and foxtail pines, with Tulare Peak’s distinctive red rock looming above the lakes. The main Franklin Lake has an old dam (a relic of mining days) and bear boxes for campers. Beyond the lakes, the trail becomes looser—think “kitty litter”—as it switchbacks to the pass. From the top, look west into the Rattlesnake Creek basin and east toward Soda Creek, with Forester Lake sitting just below the east side. East-side tread is steeper and rockier.

You’ll see restoration reroutes and “trail closed for restoration” signage near Franklin Creek—stick to the signed path. Expect stock use and the occasional manure on trail. Some reports note old, broken signposts at the pass rather than a clear sign.

Camping and logistics

Overnighters need a wilderness permit. The first legal campsite is at the Franklin/Farewell junction (about 4 miles). Excellent camping exists at and around Franklin Lakes with bear boxes provided, and many continue a short way east to Forester Lake for camping (there are hitching posts). Water is available from Franklin Creek and the lake outlets—treat it. Pets are not allowed on park trails.

Best time to hike

Late summer through early fall offers the smoothest travel. Early season (often June) can bring lingering snowfields and occasional cornice near the pass; with warming and sun-cups it’s typically passable using caution and trekking poles. Weekends can be busy to Franklin Lakes but you’ll find relative solitude beyond. Start early for cooler temps and surer footing on the sandy upper slopes; morning light pops on the red-and-orange hillsides. Lower down, Farewell Canyon can feel warmer and more humid in the afternoon.

Is it for you?

If you want a big Mineral King day or, better, a 1–2 night backpack with striking geology, lakeside camping, and expansive Sierra views, this route delivers. Day hikers often turn around at the pass after soaking in the east-side outlooks; the full push to Forester Lake as a day trip is a lot. If you prefer a shorter objective with similar scenery, stopping at Franklin Lakes is a great alternative.
