Picks Hike a Low-Profile Wilderness Elevations in Lassen National Forest range from the foothills to high peaks. The Ishi Wilderness is one of the low-elevation treats. The wilderness is a region of canyons and rushing rivers.
Trails generally follow the rivers, with a couple cutting across ridges.
That's the time to head for the high regions. The Pacific Crest Trail makes its grand way for 120 miles through the forest, moving from the granite and high mountain lakes of the northern Sierra Nevada, to the lava and broken landscape of the southernmost Cascades. We recommend the portion that crosses the Caribou Wilderness, a gentle plateau sprinkled with old volcanic cinder cones and crater peaks. Take time to wander a branch trail to one of the wilderness's many forested lakes. More on hiking in Lassen National Forest Fish Hat Creek Hat Creek is a classic, clear, cold mountain trout stream.
