Lopez Lake to Big Falls Trailhead

This 24.6-mile route begins at Lopez Lake and travels northeast to the Big Falls Trailhead, following forest roads and singletrack tiral through the Los Padres National Forest. The route offers moderate elevation gain and a mix of open ridges and shaded oak woodlands. It features waterfalls, biodiversity, swimming holes, scenic views.  It is suitable for hikers or trail runners prepared for a long day or overnight trip, with exposed sections that require sun protection and careful planning for water.

The route begins at Lopez Lake Recreation Area and follows Upper Lopez Canyon Road to Big Falls Trail. Hikers will encounter long stretches of exposed terrain, interspersed with shaded oak groves and occasional views of rolling coastal mountains. Big Falls is a stunning waterfall nestled within a wooded canyon. The trail is fairly easy to follow with little to no bushwhacking. If you are traveling in the springtime, however, be aware of poison oak in the area. 

The climb up Big Falls Trail continues to the trailhead off Hi Mountain Road, which provides access to additional trails for further exploration. Return to Lopez Lake by retracing your steps.
