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.

Reaching the summit of Cucamonga you know you worked hard! But look around and enjoy the majestic views over the San Gabriel mountains from one of the highest peaks within the mountain range. Bring appropriate gear if you hike in winter conditions. If you hike from the Icehouse Canyon Trailhead please obtain your wilderness permit from the Angeles National Forest, Baldy Ranger Station. If you prefer ascending via Middle Fork Trail, you can obtain the permit from the San Bernardino National Forest, Lytle Creek Ranger Station.
