Mt Baldy Climb

Highlight (Segment) β€’ Climb

The climb up Mount Baldy is a serious challenge, starting with a moderate grade that quickly intensifies as you ascend. As you pass through the village, the road narrows and steepens, with sections reaching 10-14% gradients and tight switchbacks that demand your focus. The final stretch to the summit, used in the Tour of California, offers a tough alpine ascent that tests even the most seasoned climbers.

Dedicated trail-goers will take a potato to the summit to leave as an offering to the potato gods. Check out the summit book, and the echo beneath the metal plate on the top of the tank!

Timber Mountain is an 8,307-foot peak right on the border of Angeles National Forest and San Bernardino National Forest. This peak is a remote-feeling peak in the Cucamonga Wilderness since the summit is at the end of a dead-end trail.
