Our nearly 1,000-acre reserve is a hiker’s dream.

Bordered by North County San Diego gems – Solana Beach, Cardiff-by-the-Sea, and Rancho Santa Fe – the San Elijo Lagoon Ecological Reserve offers 9+ miles of hiking trails via 10 trailheads.

Over 1,000 plant and animal species pass through – or make their home in – San Elijo. Many are rare or endangered. As you journey our trails connecting wetland habitats of coastal strand, salt marsh, freshwater/brackish marsh, riparian woodland, coastal sage scrub, and mixed chaparral, you’re sure to sight many species along the way.

Every day of the year, the trails are open from sunrise to sunset. For the community’s safety, trail closures occur for repairs, restoration projects, and weather hazards.

    • TERRAIN: A mostly even path to reach Annie’s Canyon Trail. However, watch out for tree roots that people could trip on. Note some soil erosion on the descending trail from Annie’s Canyon viewpoint and some stairs.

      The slot canyon’s vertical, narrow areas could aggravate claustrophobia. On the slot canyon path, there are ladder-style stairs, and on the switchback approach, you encounter wooden-plank stairs. At certain points, you need to scramble (aka use your hands + feet to propel yourself up). Be prepared for a steep climb on the return journey to the Solana Hills trailhead.

    Nice hidden gem. There is a complex of trails, but the real trail here is a small nature walk inside the lagoon that is a Figure-8 in shape.
