Elfin Forest

If you're searching for a trail system that offers a little bit of everything, rolling hills, challenging climbs, flowing singletrack, and incredible scenery, it's time to discover Elfin Forest Recreational Reserve.

Whether it's your first visit or you're heading back for another adventure, Elfin Forest has earned its reputation as one of San Diego County's premier trail running destinations. With nearly 11 miles of interconnected trails and over 700 acres of protected open space, there's always a new route to explore and another climb to conquer.

One of the best parts about Elfin Forest is its versatility. New trail runners can enjoy the wider fire roads and moderate grades, while experienced runners can link together steep climbs, technical singletrack, and longer loops for a serious training day. Along the way you'll be treated to sweeping views of Lake Olivenhain, the Pacific Ocean on clear days, and the surrounding North County hills.
