Jacks Peak East Ridge and Dicks Peak above Susie Lake

Jacks Peak is located in the heart of the Desolation Wilderness, slightly overshadowed by its big brother, Dicks Peak. Jacks Peak is a worthy summit in its own right, or -- better yet -- makes a fine days outing by combining it with a climb of Dicks Peak. More adventurous folks can use Jacks Peak as the center linchpin in a long traverse across the top of the Desolation Wilderness by traversing from Pyramid Peak in the south, northward along the Crystal Range, down to Mosquito Pass, then up Jacks, Dicks and the long traverse over to Tallac. In winter, the south face of Jacks can harbor some nice corn snow, and provides a great trans-desolation ski tour linkup.

Getting There

Because the peak sits in the middle of the Deso Wilderness, it can be reached from virtually any trailhead. Hikes from the east or south are most common.

Trailhead Name Distance¹ Highway Access
Lily Lake 6.1 89 End of Fallen Leaf Lake Road
Twin Bridges 6.7 50 2 miles east of Strawberry
Eagle Falls 12.6 89 1 mile north of Inspiration Point
Echo Lakes 4.8/7.3² 50 1 mile west of Echo Summit
Mt. Tallac 9.5³ 89 Directly across from Baldwin Beach
¹ Distances are in miles and are to the trail junction on the north side of Lake Aloha, not to the summit.
² The shorter distance is accomplished by taking the ferry across Echo Lakes.
³ For an extra 0.4 miles the summit of Mount Tallac can be reached.

Hikes from the west start near Wrights Lake and take the trail to Twin Lakes, then over the crest of the Crystal Range between Mt. Price and Peak 9,441, descending into Rockbound Valley at the foot of Jacks Peak.


Route Difficulty
East Slope Class 2
North Ridge Class 2-3
