Just to be clear … ORV use is NOT permitted on BLM lands if it is not designated for that use. Here’s relevant part of the Code of Federal Regulations:
§8341.1 Regulations governing use (of Off-Road Vehicles).
(a) The operation of off-road vehicles is permitted on those areas and trails designated as open to off-road vehicle use.
You can view the ONLY designated routes in the Morongo Basin on the map in this brochure.
Thank you for complying with the law.
