For half-day visits to the island, the caliche forest is a popular destination.
Caliche is a mineral sandcasting.
As with all park resources, it may not be collected. Take all the photographs you want. The island has been greatly altered by extensive sheep grazing, but you can still see an array of distinctive native plant species. Coreopsis and other flowering plants produce beautiful displays in the spring. Depending on the time of year, at Point Bennett you may see the California sea lion, stellar sea lion, northern elephant seal, harbor seal, northern fur seal, and Guadalupe fur seal.
