Check in at the Hidden Key Marina dock office at least 15 minutes before departure. Your guide will run through a short safety briefing and gear overview — mask, snorkel, and a flotation vest for every guest — before boarding the boat and heading out to the reef.

Snorkeling in the Florida Keys National Marine Sanctuary (2 hours) Once anchored in the sanctuary, travelers slip into the warm, turquoise waters with their guide to explore vibrant coral formations and spot tropical fish and other marine life. Since flotation vests are provided and the trip is designed for beginners, both first-timers and confident swimmers can snorkel comfortably — though guests should be comfortable in the water, as it's not suitable for non-swimmers. Touching marine life isn't allowed, keeping the reef undisturbed for everyone. This is the heart of the experience, with the full 2 hours dedicated to guided snorkeling in the water.

After snorkeling, travelers relax aboard for the ride back, with a cash bar available to grab a drink while soaking in the views before docking back at the marina.
