Guadalupe-Nipomo Dunes is the largest remaining dune system south of San Francisco and the second largest in the U.S. state of California. It encompasses an 18-mile (29 km) stretch of coastline on the Central Coast of California and extends from southern San Luis Obispo County to northern Santa Barbara County. The Guadalupe-Nipomo Dunes Complex is home to a unique dunes ecosystem as well as many endangered and threatened species of plants and animals. To protect the dunes environment, much of the Complex has been set aside for conservation. In addition, it is recognized as a National Natural Landmark. Another portion of the Dunes is utilized for recreation, such as camping and Off-Road Vehicle (ORV) use.
