Little Harbor is located in the Southern Channel Islands, on the southwest side of Santa Catalina Island, California. This site is located in an Area of Special Biological Significance (Subarea Two, North End of Little Harbor to Ben Weston Point ASBS). This site is situated between the Little Harbor campground and Shark Cove surfing beach. This site receives moderately low visitation due to its remote location and steep bluffs; however, campers and boaters explore the area. This moderately sloping site consists of moderately uneven terrain, containing crevices and folds.
