This is a difficult out and back trail to Telegraph Peak in Cucamonga Wilderness.

This trail goes by Thunder Mountain.

This particular trail is a combination of dirt roads and single-track trail. The dirt roads are the access road to the Mt. Baldy Ski Area and additional dirt road in the Mt. Baldy Ski Area itself up to Thunder Mountain. As you depart Thunder Mountain heading south to the Three Ts trail, you will transition from graded gravel to single-track hiking trail as you go down to the saddle between Thunder and Telegraph. After the saddle, there are several long switchbacks as you go up Telegraph Peak. Near the top of the peak, you will see a junction and go left up a slightly steeper section of trail approx 0.3 miles in length to the peak. Care should be taken as you approach the northwest side of the peak as the grade becomes very steep and children and animals should not be left unattended.

This hike is often punctuated by stopping at the Top of the Notch restaurant, which is at the top of the access road at the ski area. Also, to avoid the 3 miles back down to Manker Flat, you can purchase a ticket to ride the ski lift down and then walk down from the bottom of the ski lift (parking lot) to Manker Flat.

Getting Started

Parking is often plentiful along the Mt. Baldy Road at Manker Flat.

Taking Children

This would be a difficult hike for children 8 and younger. Children 12 or older would be able to do this without too much trouble, but care should be taken for the last 0.1 mile of the trail due to very steep grades.
