Plunge into the crystalline emerald waters of the Gulf Islands National Seashore to discover artificial reefs, submerged wrecks, and a kaleidoscope of Gulf marine life on a small-group guided snorkel expedition.
What to expect
The boat skims across glittering jade waters to sites where visibility regularly exceeds 20 feet, revealing a thriving artificial reef ecosystem: lionfish, flounder, sergeant majors, and the occasional nurse shark navigating coral-encrusted structures below. Your guide stays in the water with you, pointing out hidden residents and narrating the ecological story of the Gulf's surprisingly rich reef system. The return trip is pure bliss — sun-kissed, salty, and already planning your next dive.
Good to know
No prior snorkel experience required; guides provide in-water coaching. All premium gear — mask, fins, wetsuit top, and flotation vest — is provided. Morning departures see the best visibility. Confirm all-aboard time and allow 45 minutes transit back to port.
