Adventure Boat Tours

Adventure Boat Tours runs guided snorkel trips and sunset cruises from Marathon in the heart of the Florida Keys. Their signature outing heads to Sombrero Reef, a protected stretch of the Florida Keys National Marine Sanctuary marked by its historic lighthouse, where colorful coral and tropical fish wait just below the surface. The Sunset Eco History Tour trades fins for a front-row seat to the wildlife and stories of the backcountry as the sun drops over the Gulf. Private charters round out the lineup for groups who want the boat to themselves.
