MarineLab's Haunted Lagoon

 Saturday, October 24, 2026 from 6:00 to 8:30 PM. We dare you to snorkel MarineLab's Haunted Lagoon. Spooky science, ghoulish games and terrifying treats for the whole family, at MarineLab Undersea Park, 51 Shoreland Drive at mile marker 103.2 oceanside in Key Largo, at the end of Transylvania Avenue.

Yes, there is a night snorkel in the lagoon, and anyone getting in the water signs a waiver first. If the water is not your thing, there are plenty of land-based activities and games for kids of all ages.

Admission is free. For details, contact Outreach Coordinator Anne Dinsmore at [outreach@marinelab.org](mailto:outreach@marinelab.org) or 305-451-1139.
