Map Notes

The left, or West side of this 1x2 degree Backpacking Map shows 24.97 miles along the Tahoe to Yosemite Trail from the Carson Gap to Lake Alpine, plus a little extra on both sides.

The right, or East side of the map displays 29.27 miles of the Pacific Crest Trail from the Carson Gap to Ebbetts Pass, in relation to the Western position of the Tahoe to Yosemite Trail.

Both trails run through the Mokelumne Wilderness between Highway 88 and Highway 4, but on different sides of the Sierra Nevada Crest. 13 miles of twisty Highway Four separates their Southern Trailheads.

The El Dorado National Forest administers the Tahoe to Yosemite Trail through the Mokelumne Wilderness in the Western Sierra Nevada while the Pacific Crest Trail is within the Toiyabe National Forest or its Eastern section of the Mokelumne Wilderness.

This map acts as a geographic index for the trail guide and the underlaying detailed maps. Though this map gives you a rough idea of the locations of trail and terrain features you must click the RED DOTS along the Tahoe to Yosemite and Pacific Crest Trail routes to get the most out of this map. The RED DOTS are linked to the related Trail Guide page. The BLACK DOTS along the trail route are linked to detailed maps. Click them to get much better resolution on these sections of trail and a whole lot more information.

From each trail guide page you can access highly detailed maps, miles, elevations, more information and images and videos from that location.

Main Feature: The Tahoe to Yosemite Trail route

Between the Carson Gap above Highway 88 to Lake Alpine on Highway 4

This map depicts the most challenging section of the whole Tahoe to Yosemite Trail. This difficult section consists of the 9.5 miles of unmaintained trail between Summit City Creek below Fourth of July Lake, to Camp Irene on the North Fork of the Mokelumne River.

Read more about the route options you face hiking South through the Carson Gap. At this particular point you can take either the Tahoe to Yosemite Trail to Lake Alpine, or the Pacific Crest Trail to Ebbetts Pass, both on Highway 4.

Taking the option to hike the Tahoe to Yosemite Trail route means that you are going to be crossing unmaintained trail between the Summit City Junction and Camp Irene. This hike is through dangerous terrain that is physically difficult to cross, as well as difficult to navigate through.
