About Captain Mark's Dolphin Cruises
Captain Mark's Dolphin Cruises is a family-owned sightseeing cruise company that has been operating from Shelter Cove Harbour on Hilton Head Island for over thirty years. Departing from Dock C aboard the Holiday — a spacious, covered excursion vessel — the company offers daytime dolphin cruises, sunset cruises, and seasonal fireworks cruises through the waters of Broad Creek and the Intracoastal Waterway. With three decades of local experience, Captain Mark's crew knows exactly where the resident Atlantic bottlenose dolphins feed, play, and strand-feed along the mudflats.
The core dolphin watching cruise runs approximately ninety minutes and navigates through the marshlands and barrier island channels where dolphins are sighted on nearly every trip. Narration covers dolphin behaviour, tidal ecology, and the history of the Lowcountry's Sea Island culture. Sunset cruises follow a similar route timed to catch the golden-hour light over the marsh, and fireworks cruises on summer holidays offer front-row views of the Shelter Cove pyrotechnics display from the water. All cruises are family-friendly, with shaded seating, a snack bar, and restroom facilities on board.
Captain Mark's stands out for its longevity and consistency — few Hilton Head tour operators can match thirty-plus years of continuous operation from the same harbour. The operation is large enough to run daily departures year-round yet small enough that the crew recognises returning guests by name. Shelter Cove's central location makes it easy to walk to from many island resorts, and the harbour itself offers restaurants and shops for before or after the cruise. For a reliable, kid-friendly dolphin experience with sunset and fireworks options, Captain Mark's is a Hilton Head institution.
