Eco Cruise to Morris Island Lighthouse

Charleston Harbor is the front door, but the real Lowcountry is the maze of salt marsh, tidal creeks and barrier islands behind it, and a small-boat eco cruise is the best way in. This trip runs through the creeks and marsh south of the city toward Morris Island, a barrier island that has been shrinking for a century and now holds a famous landmark: the black-and-white banded Morris Island Lighthouse, which was built on dry land in the 1870s and now stands in the surf a few hundred yards off the beach. The cruise threads through the marsh grass, where bottlenose dolphins hunt, herons and egrets stalk the mud banks and oystercatchers work the shell beds. A guide explains the ecology of the tidal marsh, the history of the island, including its role in the Civil War, and why this stretch of coast is changing so quickly. For a family or a curious traveler, it is the most natural and least hurried way to spend an afternoon.

The boats are small compared with the big harbor vessels, which is what lets them get into shallow water where the wildlife is. Dolphins in the Charleston area are known for strand feeding, in which a pod herds fish up onto a mud bank and then slides up after them, and although no operator can promise to show you one, the guides know where to look and when the tide is right.

Bring binoculars if you have them, because the birdlife is excellent, from brown pelicans and ospreys to wood storks in warmer months. The marsh itself deserves attention: the cordgrass, the fiddler crab colonies on the mud flats, the oyster reefs that form the shoreline and the pungent smell of pluff mud that locals love.

The lighthouse is the visual high point. Standing on a patch of sand and surrounded by water, it makes a striking photograph, and the story of how the ocean closed in around it is a clear illustration of coastal erosion. Depending on the trip, there may be time to land on the island and walk the beach, look for shells and shark teeth and see the remnants of the old fortifications, so ask when you book whether a landing is included and whether it depends on the tide.

Timing and comfort count. Trips usually last about two hours and run several times a day in season. Morning departures are the calmest and coolest; late afternoon offers softer light. Wear sun protection, bring water and wear shoes you do not mind getting wet if a landing is planned. Insects can be a nuisance in the marsh in warm months, so a light repellent helps. The experience works for most ages, and children who like animals tend to remember it as the best part of the trip.
