With great opportunities for wildlife spotting, this easy Bolsa Chica Ecological Reserve hike takes you on a scenic loop through the 1,300+ acres of protected wetlands just minutes from the Huntington Beach. The scenery includes seabird nesting islands, fresh and saltwater marsh, mudflats, active riparian river banks, and water. Over 200 species of birds have been spotted here, and it’s a popular stopover on bird migration routes. The hike is great for families with opportunities to shorten the route if 4.5 miles is too long.
