Biscayne National Park Winter Eco-Adventures: Boca Chita Key & Bay Boat Cruises

About this adventure

Covering 173,000 acres—95% of which is sparkling subtropical water—Biscayne National Park is America's largest marine sanctuary. During South Florida's crisp winter dry season, calm turquoise waters and mild 75°F days create ideal conditions for family boat excursions departing from Convoy Point. Guided 3.5-hour heritage cruises take passengers across the bay to Boca Chita Key, the park's most visited island, featuring a picturesque 1930s coral-rock ornamental lighthouse, shaded coconut palm picnic grounds, and a scenic seaside walking trail with crystal-clear lagoon views. Families with babies and small children can explore the mainland Dante Fascell Visitor Center free of charge, enjoying interactive touch tables, local art exhibits, and a scenic bayside boardwalk trail lined with mangroves. Guided boat eco-cruises welcome children of all ages (life vests provided in all youth sizes); advance bookings through the official Biscayne National Park Institute are highly recommended.
