Pinyon Mountain Valley offers a scenic and very challenging ride through Pinyon Canyon in the rugged desert terrain of Anza-Borrego Desert State Park. The ride starts off easy but things change quickly as drivers will start to encounter multiple obstacles. The Squeeze is a narrow, rocky passage that will wreak havoc on wild vehicles. Pinyon Dropoff is another obstacle that is very steep on an uneven rocky surface. Additional steep climbs and rocky sections also present more challenge. The ride is rated as difficult and should only be attempted by experienced drivers operating hard-core modified vehicles. Lockers are not required but will make it easier. Avoid the area during rainstorms due to flash flood potential.
