Disappearing Island Dolphin Tour

The Disappearing Island Dolphin Tour is only available when the moon and tides align just right — and that's exactly what makes it special. You get everything on a regular dolphin tour, plus the boat stops at a sandbar island that only exists for a few hours at low tide. Guests hop off, walk around, and look for sand dollars, starfish, and shells before the island disappears back beneath the water.

It's a 2-hour experience that covers more ground than the standard cruise, and the combination of wildlife watching and a literal disappearing island makes it one of the most memorable things you can do on Hilton Head. Your naturalist guide narrates the whole trip and explains the tidal dynamics that create the island.

Because availability depends on the tides, this tour doesn't run every day. Check the calendar and book ahead — when it's available, it sells out quickly.
