Five places that explain Sullivan’s Island
The island is best understood as a mix of beach town, protected maritime landscape and strategic harbor outpost. These stops give you a strong first visit without trying to turn the day into a checklist.
Fort Moultrie
Walk through layers of American coastal defense, from the Revolutionary War site to the brick fort that served through the 20th century.
NPS GuideSullivan’s Island Beach
Enjoy 3.5 miles of Atlantic shoreline with public beach paths throughout the island. There are no lifeguards, so ocean conditions matter.

History stop
Fort Moultrie is the island’s essential historic site.
The first fortification here helped defend Charleston from a British naval attack on June 28, 1776. The National Park Service interprets the site’s later coastal-defense history as well, including the brick fort that remains today.
The current NPS schedule lists Fort Moultrie’s grounds, parking area and restrooms as open daily from 9:00 a.m. to 4:30 p.m. The visitor center is at 1214 Middle Street. Check the NPS page before your visit because hours, fees and programs can change.
Plan a Fort Moultrie Visit
Beach + nature
Walk the island where maritime forest meets the Atlantic.
The Town describes the Sullivan’s Island Nature Trail as two miles of paths linking the Station 16 beach area with Fort Moultrie and Charleston Light. It is one of the easiest ways to experience the island’s maritime habitat without leaving the developed part of town far behind.
Beach access is available from numerous public paths. Accessible beach routes are available at Station 26, Station 21 and Station 18½, and part of the Nature Trail includes ADA matting between Stations 18 and 18½.

Battery Gadsden is now a library—and a link to Edgar Allan Poe.
The Edgar Allan Poe/Sullivan’s Island Library occupies renovated Battery Gadsden, a former Spanish-American War-era gun battery. Poe was stationed on Sullivan’s Island in 1827–1828 and later used the island as the setting for The Gold-Bug.
It is a good stop when you want something more local and less obvious than the beach-and-fort circuit. Check Charleston County Public Library for current branch hours before going.

Parks, viewpoints and low-key stops
Not every stop needs to be a major attraction. Sullivan’s Island has small public spaces that work well between the beach, lunch and historic sites.
Thomson Park at Breach Inlet
A beachside historic site and viewpoint near Breach Inlet. The Town specifically warns that swimming is not allowed here because of strong currents and undertow.
Town Parks GuidePoe Avenue Park
A neighborhood park at Station 17 and Poe Avenue with two tennis courts, a bottle-filling station and a contemporary playground.
Town Parks GuideCharleston Harbor Views
The western side of the island opens toward Charleston Harbor, giving a very different feel from the Atlantic beach and a useful geographic sense of why the island mattered militarily.
Island OverviewBefore you go
A few Sullivan’s Island rules matter more than they do at a typical beach stop.
The Town allows public beach parking in the public right-of-way, but all four tires must be off the pavement and beach paths cannot be blocked. There are no lifeguards on duty. Alcohol is prohibited on streets, boardwalks and beaches, and glass, polystyrene and plastic containers are not allowed on the beach.
If you plan to bring a dog, review the Town’s current dog-license and beach-hour rules before you arrive. Rules and seasonal access details can change, so the official Town beach page is the right final check.
