Unalayee’s unique location in the heart of the Trinity Alps Wilderness, and within walking distance of the Russian and Marble Mountain Wildernesses, makes it the perfect trailhead to a backpacking adventure. Our wilderness summer camp is surrounded by pinnacles and peaks, hundreds of high-altitude lakes, ribbons of rivers, limestone caverns and caves, meadows brimming with wildflowers, and tangles of trails begging for exploration. Each session, Unalayee offers multiple Trail Programs - ranging from 11 to 15 days - that provide extended backpacking trips into this remarkable landscape. All of our trail programs incorporate some level of wilderness survival skills and may include 24-hour solos or cross-country terrain. Choose between Wild, Hiking, or Summit to Summit!
