Upper Sespe Creek flows along scenic Highway 33, which provides access for popular day use recreation activities, including swimming, wading, picnicking, day hiking, horseback riding, and rock climbing in the spectacular Sespe Gorge. Dominated by the Piedra Blanca sandstone rock outcrops on the slopes above, the creek’s riparian vegetation offers dramatic spring and fall colors in contrast with rocky cliffs and dark green big cone Douglas firs. Identified by scientists as an area of high ecological significance, this free flowing stream is one of the best remaining low elevation and relatively intact aquatic ecosystems in the central and southern California region. The creek supports one of the few populations of endangered steelhead trout in southern California and one of the largest populations of endangered arroyo toad.
The Upper Sespe Creek segment is 19.6 miles
