This reserve protects 110,000 acres of coastal lands and marine estuaries at the northern end of the Ten Thousand Islands, just south of Naples and north of Marco Island. A two-story learning center features an auditorium where guests watch an excellent video, along with a marine touch tank and 2300-gallon aquarium with a climb-in bubble. From there, popular activities include kayak and boating tours, a nature walk and birding excursions.
