Rainbow Basin Natural Area is located 8 miles north of Barstow, California, off Irwin Road (not Fort Irwin Road). The main acess route is Fossil Bed Road. Rainbow Basin is designated as an Area of Critical Environmental Concern due to landscape features and paleontological resources in the area.
Many visitors come to see exciting multi-colored rock formations and walk the scenic canyons. A variety of desert wildlife is found here, including the desert tortoise. Vehicle trespass is a major concern, so all routes not signed as “open” are CLOSED to vehicles.
Camping Opportunities are offered in the adjacent Owl Canyon.
