Yolla Bolly-Middle Eel Wilderness

Yolla Bolly-Middle Eel Wilderness is a protected natural area in Mendocino County featuring expansive mountains and forests. The landscape includes forested valleys, mountain ridges, and alpine peaks that create a diverse terrain.

The area received protected status as a primitive zone in 1927 through the U.S. Forest Service. It gained official wilderness designation through the Wilderness Act of 1964.

The name comes from the Wintun language, where Yo-la means snow-covered and Bo-li refers to a high peak. These words reflect the indigenous connection to this mountainous land.

The area can be accessed through 15 trailheads surrounding the boundary, with entry points from the towns of Covelo, Ruth, and Corning. Visitors should prepare for varying conditions since elevation and terrain differ significantly across the region.

The area contains headwaters for multiple rivers, including the Middle Fork and North Fork of the Eel River. Both river sections hold Wild and Scenic Rivers designation, making them among the region's most important water systems.
