One of the simple joys of a Gulf Coast stay is watching wild bottlenose dolphins play in the calm bay water. Near Madeira Beach and Treasure Island, sightings are common — sometimes right from your dock — and easy dolphin-watching cruises make them almost a sure thing.
Where to see dolphins
Dolphins frequent the calm Intracoastal Waterway and passes between the barrier islands. John's Pass in Madeira Beach is the main hub for dolphin-watching tours, and many of SEASALT's waterfront homes look out over water where dolphins regularly pass by.
Tours vs. going yourself
Dedicated dolphin cruises from John's Pass are short, affordable and family-friendly, with guides who know where the pods gather. If you'd rather explore on your own, a kayak or paddleboard on the calm bay side often brings you close to dolphins and manatees — just keep a respectful distance.
Best times to look
Dolphins are active year-round here. Early morning and around sunset tend to be especially good, when the water is calm and boat traffic is lighter. Watch for their dorsal fins breaking the surface, often near passes and channel markers.
