Dolphins on the Edge of the Map: Snorkeling Key West’s Backcountry
Small group, big water: wild dolphins on their terms and a snorkel stop tailored to the day.
Morning in the Lower Keys arrives in colors you can taste—lime over teal, a dash of cobalt where the ocean deepens. The marina at The Perry Hotel stirs to life, dock lines humming as the tide breathes in and out. Your boat, a lean 25–27-foot runabout with shade overhead and sun-warmed cushions up front, noses toward open water. Six seats. One small crew. The Gulf and Atlantic meeting at the island’s doorstep. The sea looks playful today. It dares you to come see what’s moving under its glass.
Trail Wisdom
Respect the Dolphins’ Space
Admire from a distance and never try to feed or swim with wild dolphins; staying 50 yards or more keeps encounters safe and natural.
Aim for Morning Calm
Early departures often mean lighter winds and better visibility—ideal for both wildlife viewing and comfortable snorkeling.
Go Reef-Safe
Use mineral-based, reef-safe sunscreen or a long-sleeve rash guard to protect skin without harming coral.
Prep for Motion
If you’re prone to seasickness, take non-drowsy meds 30–60 minutes before departure and focus on the horizon while underway.

Wildlife
Bottlenose dolphin, Green sea turtle
Conservation Note
Follow NOAA’s dolphin-viewing guidelines, never feed wildlife, and use reef-safe sunscreen. Avoid standing on or touching coral; anchor only at sand or use mooring buoys to protect habitat.
Key West grew from the sea—wrecking, sponging, and fishing shaped the island long before tourism. The Florida Keys National Marine Sanctuary, created in 1990, protects these waters after decades of ship groundings and environmental threats.
