Why it works

Hetch Hetchy is Yosemite's least-visited major destination despite offering waterfalls and granite walls rivaling Yosemite Valley — the reservoir's dam access and the surrounding trail network require accurate mapping for visitors exploring this quieter corner of the park. The Grand Canyon of the Tuolumne's remote backcountry terrain requires detailed topographic mapping for safe navigation. Waterproof construction survives the Sierra Nevada's afternoon thunderstorms and the variable weather common in Yosemite's high country.

Ideal for

Hikers, backpackers, and solitude seekers exploring Hetch Hetchy, the Grand Canyon of the Tuolumne, and the northwestern Yosemite backcountry. See also NGTI308 (Yosemite NE, Tuolumne Meadows) for adjacent coverage.
