Olivenhain Municipal Water District is devoted to the operation of the Elfin Forest Recreational Reserve and to providing all visitors with a unique recreational, educational, and environmental experience.

This spectacular 784-acre open space park and recreational area was developed by OMWD, in partnership with the San Diego County Water Authority and the U.S. Department of the Interior-Bureau of Land Management, as an element of the Olivenhain Water Storage Project.

The Reserve offers approximately 11 miles of hiking, mountain biking, equestrian trails, primitive picnic areas, and scenic mountain viewing points. In addition, the natural beauty of the Reserve includes such native plant communities as oak riparian, oak woodland, coastal sage scrub and chaparral.

Owned by the Authority and operated and managed by OMWD, the Reserve has been designed to unify the interests of domestic water supply development, natural resources management and recreational opportunities. Park rangers conduct guided group tours and student exploration programs to promote environmental awareness and preservation of local watersheds. All wildlife and natural resources at the Reserve are fully protected so that future generations may also enjoy these wonders.
