The engine hums low and steady as the coastline drops away—mangrove roots like the fingers of an old map tracing channels into a watery maze. Sea air thick with salt and citrus lifts as the captain eases into the 10,000 Islands Wildlife Refuge. Within minutes a dorsal fin arcs like a punctuation mark; dolphins appear curious, cutting the surface and daring you to keep up. The first hour is water, wildlife and interpretation: a Florida Master Naturalist sketches the food web between mangroves, estuaries and the birds that depend on them. The second hour shifts tone—the boat slips into a shallow pass, and you land on an uninhabited barrier island to hunt for shells and stand where the Gulf rolls its slow decisions onto the sand.

Adventure Tips
Morning departures in summer
From June to October choose a morning tour to avoid afternoon storms and higher temperatures.
Bring water and sun protection
Florida sun is intense—carry at least one liter of water, sunscreen, and a brimmed hat for the boat and beach landing.
Wear water-friendly footwear
Expect shallow wading when landing on the island—sandals with straps or water shoes make the beach stop easier.
Respect wildlife distances
Follow the captain and naturalist’s guidance to avoid disturbing dolphins, nesting birds, or sea turtles when on the water or beach.

Conservation
The refuge is protected to preserve nesting and foraging habitat—practice leave-no-trace during beach stops and avoid removing live shells or disturbing wildlife.
