Island Ferry's Dolphin-Snorkeling Cruise takes you snorkeling by boat to Shell Key, and to see dolphins at the same time! See dolphins in their natural habitat, along with manatees, rays, and wild birds. Go snorkeling and shelling on Shell Key Preserve, where you'll find hermit crabs, conchs, rays, horseshoe crabs, and more. Island Ferry is not a drop-off service, but rather the boat stays at Shell Key with you for the entire time. You can take a break from snorkeling and shelling, and sit on our shaded boats with a cold drink. And while you and your family are in the water, the Island Ferry crew stands watch on lifeguard duty. So we keep everyone safe! We provide the snorkel gear and the floating noodles.

We had a great morning with our captain Troy! We saw several dolphins very close to our boat, and it was a beautiful morning to stroll on Shell Key. Would definitely do this trip again!

Captain Noel was amazing. He took the time to help kids find sand dollars, hermet crabs on sand bar and then took them to shell island. He was full of information on the trip there and back. We have done other shelling trips in the past this was by far the best.
