North Shore Trail Professional Review and Guide
"Batiquitos Lagoon is a 600-acre wetland fed by Encinitas Creek, San Marcos Creek, and tidal flows. The lagoon rests in South Carlsbad, bordering the north edge of Leucadia. The coastal preserve serves as a sanctuary for rare, threatened, and endangered birds, animals, and plants. It is also a migratory waterfowl habitat with saltwater marshes, mudflats, salt flats, palms, eucalyptus trees, and native sage scrub vegetation. This wide trail follows the tranquil northern shoreline of the lagoon, beginning just east of I-5, and heads east to the inland end of the lagoon by El Camino Real. The western portion of the path is an 18-station interpretive trail with an accompanying pamphlet, available at the trailhead nature center."
