Isle of Palms holds about 840 acres of salt marsh, and until this year almost nothing on the island explained it. That changed at the Public Dock on the Intracoastal Waterway side of the Isle of Palms Marina. Fourteen illustrated interpretive signs now stand along the dock and the walkway beside it, and they are free to read from sunrise to sunset. The timing works in the island's favor. Sea turtle season officially closes October 31, and the City's website currently runs a beach renourishment construction banner across the top of its pages. As the beach heads into its quiet season, the side of the island that stays active all year finally has a way to be read.
Fourteen signs on the Intracoastal side
The City calls the project the Public Dock Eco-education Project. The signs were installed earlier in 2026 and formally recognized with a ribbon cutting in early October. The City scheduled a free Stroll & Learn ahead of the ceremony, with naturalists from the Island Turtle Team, Barrier Island Eco Tours and Holy City Birding leading people from sign to sign.
Laura Lovins, who chairs the City's Environmental Advisory Committee, and committee member Susan Hill Smith led the project with support from the full committee and City staff. The art and design came from Kaitlyn Hackathorn, a local graphic designer and illustrator who previously worked for the S.C. Department of Natural Resources. Sponsors were The Outpost at Isle of Palms Marina, Islander 71 and Barrier Island Eco Tours.
The City's announcement compares the format to signage in national and state parks. Subjects run from seabirds, shorebirds and wading birds to fish, sharks, manatees, dolphins and sea turtles. Several panels explain how pluff mud and cordgrass depend on each other. Seven smaller "Salt Marsh Creature" signs line the walkway between the dock and Islander 71, so a walk to dinner doubles as a short field lesson. Every design is also posted as a PDF on the City's education and outreach page, which helps anyone who wants to read up before going or name the bird they saw after.
Lovins put the project's reasoning plainly in the City's release:
"While we often focus on the beach, we must also recognize, protect and celebrate the critically important salt marsh and tidal ecosystems around us."
Turtle season ends October 31. The marsh keeps working all year.
Turtle season is the beach's best-known wildlife story, and it had a good year. According to Lucky Dog News, the 2026 season produced 41 loggerhead nests on Isle of Palms and 17 on Sullivan's Island, and 4,824 hatchlings reached the ocean from the two islands combined. The Island Turtle Team's dawn patrols on IOP ended August 15, and a paid overnight worker continues monitoring until the season officially ends October 31. The Sea Turtle Nest Monitoring System shows the same 41 nests for Isle of Palms, along with 47 false crawls, as of its September 29, 2026 update.
The marsh behind the island runs on a longer schedule. The City's release notes that more than 75% of the region's commercial and recreational fish species rely on salt marshes and related estuaries, as do sea turtles and some dolphins. South Carolina has more salt marsh than any other East Coast state, somewhere between 350,000 and 500,000 acres depending on how it is measured. The marina sits at the edge of a largely protected stretch of tidal wetlands to the northeast. Many of the animals the beach celebrates in summer depend on the water behind the island, and the dock now explains that connection in illustrated panels.
October is also a strong month on that water. The SCDNR saltwater fishing trends page describes October as typically good for Charleston inshore fishing, with redfish feeding through the tide cycles and trout taking shrimp and mullet around moving water. That is general seasonal guidance, not a 2026 catch report.
A morning at 41st Avenue, in order
Because the dock and its neighbors keep different hours, a fall visit works best in sequence. Here is one way to put the pieces together, based on posted schedules.
- Park. The City provides 16 resident-only spaces by the dock, free for Isle of Palms or Wild Dunes residents with proper credentials. Paid parking and golf-cart parking are along 41st Avenue near the marina entrance.
- Coffee first. The Outpost, the marina's ship store, opens at 8 a.m. It serves breakfast from 8 to 11, has a full coffee bar, and stocks bait and tackle, grocery provisions, beer and wine. The store closes at 6 p.m.
- Walk the signs. The main panels sit at the Public Dock, 50 41st Ave. The seven "Salt Marsh Creature" signs continue along the walkway toward Islander 71.
- Get on the water or drop a line. The Public Dock is free and open daily from sunrise to sunset. Kayak and paddleboard launching are allowed, and so is fishing.
- Lunch or later. The Outpost serves lunch from 11 a.m. to 3 p.m. Islander 71 opens at 4 p.m. Monday through Friday and at noon on weekends, closing at 9 p.m. every day. Its Fall 2026 menu includes oysters on the half shell at market price, chilled shrimp cocktail for $16, fresh-catch ceviche for $22 and yellowfin tuna poke for $20.
The gap between those hours matters on weekdays. A sunrise walk and an Islander 71 dinner don't overlap, but The Outpost covers the morning and midday.
Past the end of the dock
The signs describe the marsh, and the marina's operators take people into it. Barrier Island Eco Tours runs naturalist-led trips from the marina all year. Its Capers Island Wildlife Exploration runs from 9 a.m. to 12:30 p.m. through salt marsh and tidal creeks, priced at $60 per adult, $45 per child and $15 per infant. The 2.5-hour Sunset Dolphin Cruise moves to an off-season schedule of Sunday, Wednesday and Friday evenings, with departure times set by sunset. Posted prices are $55 per adult, $40 per child and $15 per infant. Its private blue-crabbing charters to Capers Island are listed for May through November. They combine crabbing, an ecology cruise and a beach crab boil.
For anglers following SCDNR's October outlook, the same company offers a four-hour private inshore fishing charter for up to six people, targeting redfish, sea trout, flounder and sharks. The page lists a starting rate of $550 for two people plus $75 for each additional angler under a "price per hour" heading, so confirm the total for the four hours when booking. The marina's directory also lists Charleston Fish Finder, Shore Thang Charters, Fish Call Charters, Southern Breeze Charters and Charleston Sport Fishing, along with gas and diesel for boats.
If you'd rather go on your own, the marina rents single and tandem kayaks and paddleboards in two- or four-hour blocks. It also rents pontoon boats, center consoles and Key West skiffs. The rental page lists durations but not prices, so call ahead for rates.
What the dock asks of visitors
The signs teach and the dock rules set limits. The City's posted rules prohibit:
- swimming
- littering
- unleashed pets and pet waste left behind
- smoking
- alcohol
- mooring motorized vessels or watercraft
The page allows fishing but doesn't address crabbing either way, so check with the marina before setting a trap off the dock. The no-alcohol rule applies to the dock itself, and the beer and wine The Outpost sells stay at the store.
Birders get one more item for the calendar. Holy City Birding usually holds its free walks on the third Saturday of the month. The next two are off the island, at Carr-Richardson Park on October 17 and Melton Peter Demetre Park on November 21. After a morning with the dock's wading-bird panels, either walk is a good next step.
At Smith Spencer Real Estate, we pay attention to the parts of Isle of Palms that run on their own schedule, including the marsh side behind 41st Avenue. If the Intracoastal side of the island is starting to matter in how you think about your own place here, we're glad to talk it through. Contact Us.
