Trails

The Madora Lake Loop
This trail is a 1.5 mile round-trip, and is relatively flat and shaded. This is one of the better hikes in the area for birdwatching, and the lake can be a fun spot for kids, with its population of non-native bullfrog. The lake is closed to swimming. The trailhead is at the Madora Lake parking lot, just inside the park’s eastern (main) boundary.
The Eureka Peak Trail
This is a strenuous 3-mile round-trip, but offers amazing views of the surrounding area. On a clear day, Lassen Peak can be visible to the north. It departs from the Eureka Lake day use area, which is a rough, 1.5 mile drive from the Johnsville Ski Bowl parking lot.
The Campground-Museum Trail
As its name implies, this trail runs from the campground to the museum. It is a little over a mile, and is relatively flat and mostly shaded. It parallels Jamison Creek for much of its length.
The Lakes Basin
The Lakes Basin Trail can be accessed via the Grass Lake Trailhead at the Jamison Mine parking lot. This trail is only in the park for a mile, and it is fairly steep and rocky. It provides access for Grass, Smith, Jamison and Wades Lakes, as well as access to the Pacific Crest Trail and the myriad lakes and waterways in the Lakes Basin Recreation Area (US Forest Service).
