Peter Grubb Hut

Peter Grubb Hut is located below Castle Peak in Round Valley, 3 miles north of the Castle Peak trailhead near I-80. Expect approximately 800′ of elevation gain. The route is poorly marked by orange triangles mounted obscurely in trees at 100-200 yard intervals. Overnight parking is available at the California Sno-Park at the Boreal-Castle Peak exit on I-80. Park on the frontage road east of the Boreal Inn and walk back under the freeway to the trailhead. Topo map: Norden 7-1/2′ quad.

There are day trip possibilities to Paradise Valley, Basin Peak, Castle Peak, and Sand Ridge Lake. Round Valley is a good instructional and practice area for skiers. The hut is just off the Pacific Crest Trail and is a popular destination for day trippers; daytime privacy and security are minimal.
