Captain Anton, Tideline Tours’ coastal geologist and 30-year Folly Beach native, guides passengers above the azure waves and emerald spartina grasses of Folly Island. During a two-hour salt-marsh adventure, groups of up to 12 scan from port to starboard as mullet, pelicans, and dolphins frolic in the water to the beat of Captain Anton’s informative narration.

Briny sulfur and saltwater aromas waft across the vessel as it navigates maze-like tidal creeks, parting the waves in front of the Morris Island Lighthouse. Collected by Captain Anton, hydrophone-recorded dolphin sounds echo distinctively across sandbars throughout the jaunt, distracting adolescent bottlenoses trying to pay attention in class and gleefully confounding human ears.
