The bottlenose dolphins of Hilton Head Island practice a hunting technique documented in only a handful of places on Earth: strand feeding, in which the animals drive fish onto a mudbank, beach themselves deliberately, and slide back into the water.
Broad Creek and the tidal reaches around Shelter Cove sit within that narrow range.
Shelter Cove Marina opened on the island's Atlantic side in the early 1980s, dredged from the marsh at 1 Shelter Cove Lane and built as a deep-water harbour for a barrier island that had, until the 1956 bridge, no road connection to the mainland at all. Hilton Head Island covers roughly 42 square miles of maritime forest, salt marsh, and beach, and its waters form part of the Port Royal Sound estuarine system — one of the deepest natural sounds on the southeastern seaboard, and a nursery for shrimp, menhaden, and the red drum that draw predators inshore. Hilton Head dolphin tours Shelter Cove operate directly into that system, threading Broad Creek toward Calibogue Sound.
The estuary matters ecologically because of scale. Spartina alterniflora — smooth cordgrass — carpets the marsh in stands that flood and drain twice daily, exporting detritus that feeds the whole food web. Tidal range here runs to roughly seven feet, which reshapes the creek's navigable channels hour by hour and concentrates baitfish at the mouths of feeder creeks. Resident dolphin pods number in the low hundreds across the region, and researchers have catalogued individuals by dorsal-fin notch patterns since the 1990s, tracking site fidelity that keeps the same animals in the same creeks across decades.
The marina itself is a working one: charter berths, shrimp boats, and a public boardwalk under live oaks hung with Spanish moss. Free entry to marina area; individual tour fees apply, so the docks stay open to walkers as well as passengers. Hours run 07:00–21:00 daily. Around it, the island's conservation architecture is unusual — Sea Pines, established in 1956, pioneered covenant-based development that buried utility lines, limited building heights below the tree canopy, and preserved the forest that still screens most of the shoreline. That restraint is why the view from a boat leaving Shelter Cove reads as marsh and treeline rather than towers. Ospreys nest on channel markers. Brown pelicans work the sound in single file. Hilton Head dolphin tours shelter cove tickets are, in practice, entry to a protected estuary that has been studied, mapped, and defended for seventy years.
