Responsible Wildlife Viewing
Keep your distance. Federal law requires staying at least 50 yards from dolphins and sea turtles. Enjoy them from a distance — they'll often come closer on their own terms.
Never feed wildlife. Feeding dolphins, birds, or fish changes their natural behavior and can make them sick. It's also illegal under the Marine Mammal Protection Act.
Respect nesting areas. Roped-off sections of beach protect nesting sea turtles and shorebirds (May-August). Stay out of these areas — even footprints can collapse a nest.
Don't chase or corner animals. If a dolphin or manatee swims away from your boat, don't follow. Let wildlife approach you naturally.
Pick up your trash. Plastic bags, fishing line, and food wrappers are deadly to marine life. Pack out everything you bring in.
About Dolphin Sightings
We do not offer dedicated dolphin tours. Dolphins are wild animals, so sightings can never be guaranteed.
You may still spot dolphins during the shuttle ride or while exploring by pontoon near the pass. Watch from a respectful distance and let wildlife approach on its own terms.
