Nature
Wildlife is abundant in the area. Black bears and foxes live in the more remote areas of the park and Mountain Lions can occasionally be seen along the slopes of Eureka Peak, and many deer, weasels, porcupines, bobcats, and other mammals are spotted in the unit. Numerous species of Birds are also found in the park. Bird watchers come to Plumas-Eureka to see Pileated Woodpeckers, Calliope Hummingbirds, and Saw-Whet Owls, to name just a few of the delightful Sierran birds found here. Madora Lake and Eureka Lake are both in the park and a number of other lakes are located on U.S. Forest Service land just outside the park boundary. Trails, many of them actually old mining-era roads, reach out from Plumas-Eureka to these lakes, and to other outstanding High Sierra features.
