The Shea Pit and Osborne Wash Area is a large desert riding location that is home to the annual Parker 400 Desert Race. This extensive network of trails, located east of Parker, is characterized by rugged 4x4 routes and sandy washes, with the landscape dotted with various cactuses and creosote bushes. The area has multiple access points and is defined in part by post and cable boundaries that delineate the race pit and spectator areas. The braided Osborne Wash, which is adjacent to the spectator area, also offers excellent riding.
Riders are permitted to primitive camp throughout the area, but there are no amenities, so it is essential to bring your own water and shade. For additional services, the nearby towns of Parker and Lake Havasu City provide a range of recreational opportunities and supplies. The area is a popular destination during the spring, fall, and winter months.Dirt Bike Trail System
