Cucamonga Wilderness

Cucamonga Wilderness is a 13,007-acre federally protected Wilderness Area in California, managed by the Forest Service. The landscape is primitive backcountry where no roads, motors, or mechanized travel are permitted—it exists as true non-motorized wilderness.

Hiking and backpacking are the primary ways to experience this area. The terrain and elevation create seasonal access windows; spring and early summer can bring snow and runoff, while fall offers stable conditions. Summer is the most reliable season for travel, though afternoons can bring thunderstorms in the high country.

Visitors must follow strict Wilderness rules: no mountain bikes, no stock unless specifically allowed by Forest Service regulations, and full Leave No Trace practices apply. There are no facilities, no maintained road access into the core, and solitude is the norm. This is backcountry hiking in its traditional form—self-reliant travel through undeveloped terrain.
