NAPLES ECO TOUR FIELD GUIDE
Into the Quiet of the 10,000 Islands: A Naturalist-Led Cruise Aboard the Calusa Spirit
A 2.5-hour powered-catamaran eco tour from Marco Island that visits an uninhabited island and offers close encounters with dolphins, manatees and coastal wildlife — this guide explains what to expect and how to prepare.
Into the Quiet of the 10,000 Islands: A Naturalist-Led Cruise Aboard the Calusa Spirit.
Climb aboard the Calusa Spirit, a roomy 45 ft powered catamaran, and head south from Marco Island into the tangled waterways of the 10,000 Islands. Over about two and a half hours an onboard naturalist narrates the coastal ecology and history as the boat moves through dolphin‑scattered water toward a secluded, uninhabited island where passengers step ashore to walk the shell‑strewn shore before returning to Marco Island.
