Where to Go Snorkeling Near Shell Key Preserve

Most Shell Key snorkeling tours launch from St. Pete Beach or Tierra Verde, with a short kayak trip (~4 miles round trip) or boat ride out to the preserve itself. The snorkeling typically happens on the Gulf side of the key or in the grass flats just off the island, where you’ll find sea urchins, sand dollars, rays, sea stars, and small reef fish. Some longer trips may also include stops at nearby Egmont or Outback Keys for additional snorkeling, swimming, or beachcombing.

If you want a more active day, try a combo kayak/snorkel tour that lets you paddle out to Shell Key, exploring the mangrove channels before diving into the water to cool off and explore.
