The turning for Fossil Falls is signed from US 395, a junction half way (22 miles) between Indian Wells and Olancha, in generally empty and undeveloped region. The side road is initially paved then has a surface of smooth red ash, running below the southern slopes of Red Hill. A right fork after half a mile crosses more ash, now mixed with patches of lava, ending in another mile at a relatively large parking area, from where the ravine is 0.2 miles away, along a level though somewhat uneven trail over the lava flow. A spur road leads to an area used for primitive camping, while the first road continues, initially to a viewpoint of Red Hill, which is a privately owned feature with a scoria mine at its base, then leads on to other, more remote cinder cones and lava deposits. The main viewpoint of the falls is on the northwest rim of the ravine, but it is easy to cross the streambed above the drop-off and explore the opposite rim as well, walking over rather more undulating lava. All this area has good, long distance views west, across the highway to the steep east face of the Sierra Nevada, the foothills of which are just 2 miles away. The climbing route into the ravine is initially via a series of short steps, then down a taller crack, aided by several wedged boulders, past a series of sculpted fins and out to a flat area beside a graffiti-covered pothole and arch. The canyon opens out just below, to the bench at the brink of the lower falls, which are not climbable.
