Trail starts at the dead end of Vanalden Ave, starts going uphill and soon reaches an unmarked junction. From here to the left the side trail leads to the sandstone cave that has a thin ceiling with holes in it, one can go atop and look inside the cave from above. Unfortunately, the cave is covered with trash and graffiti.
Continuing straight at the junction, the trail crosses Mulholland Dr which is a single track dirt road here, goes past the water tank and leads to a hilltop called Vanalden Vista. View from here include inhabited and uninhabited slopes of Santa Monica Mountains and San Fernando Valley.
