Mount Baldy Resort to Cucamonga Peak is a challenging out-and-back hike that takes you from the serene setting at Mount Baldy Resort to the breathtaking summit of Cucamonga Peak, one of the most iconic peaks in Southern California’s San Gabriel Mountains. Covering 16.6 miles round trip, this strenuous trail offers hikers an opportunity to experience diverse landscapes, sweeping views, and significant elevation gain.

DESCRIPTION
Start your journey at Mount Baldy Resort, where parking and access to the trailhead are available. The route follows the Three T’s Trail, named for Thunder Mountain, Telegraph Peak, and Timber Mountain. This section is strenuous, with a mix of steep climbs and descents, but it rewards you with panoramic views of the surrounding peaks and valleys. After passing Timber Mountain, you’ll reach Icehouse Saddle, a critical junction where you’ll turn onto the Cucamonga Peak Trail.

The final ascent to Cucamonga Peak is demanding, with steep switchbacks and loose terrain.
