Shell Key Boat Tours & Snorkeling Adventures

Shell Key Preserve — sandbars, seashells & snorkeling, all to yourself

Call (410) 967-7898

Shell Key Preserve, just off the Pinellas Coast near St. Pete Beach, is one of Florida's best-kept secrets — a pristine barrier island with shallow turquoise water, abundant seashells, and some of the clearest snorkeling on the Gulf Coast. And the only way to get there is by boat.

Our private Shell Key boat tours take up to 6 guests with your own captain. Wade the sandbars hunting for sand dollars, conch shells and even shark teeth, snorkel over seagrass beds full of marine life, and relax on beaches most visitors never see. All snorkeling gear and instruction included.

Shell Key Snorkeling Tours

Snorkel the calm, clear waters around Shell Key — tropical fish, rays, and seagrass beds make it one of the best snorkeling spots near St. Pete Beach. Gear and instruction included.

Shelling on Shell Key

The island lives up to its name. Find sand dollars, conch shells, starfish and even fossilized shark teeth along the shoreline and shifting sandbars.

Sandbar Time & Swimming

Anchor in waist-deep turquoise water, set up the floating fun, and enjoy a private slice of paradise with just your group.
