Fodor's Expert Review San Elijo Lagoon Conservancy
Between Solana Beach and Encinitas, this is the most complex of the estuary systems in San Diego North County. A 7-mile network of trails surrounds the 979 reserve, where more than 700 species of plants, fish, and birds (many of them migratory) live. Be sure to stop by the San Elijo Lagoon Nature Centre. The center, open 9 to 5 daily, offers museum-quality exhibits about the region and a viewing deck overlooking the estuary. Docents offer free public walks every Saturday at 10 am.
