Nature Adventures, based in Mt Pleasant, recently received the “Gold Level” recognition by the South Carolina Nature-Based Tourism Association. They operate kayak tours from several locations but the most convenient to visitors to Charleston not using a car is the Mt Pleasant Shem Creek. Choose a saltwater tour; they offer a variety of times and lengths of tours. Or rent a kayak from this location. They recommend reservations to assure that your kayak is waiting for you when you arrive at the dock.
Their location at 483 West Coleman Blvd, Mt. Pleasant 29464 is accessible by Green Taxi or public transit. At present, the closest stop on Route 40 is Patriot’s Point in the USS Yorktown State Park. The walk from this stop is about 2 miles following W Coleman Blvd. The bike ride from downtown is about five miles but you must cross the bridge which arcs making the ride a bit more challenging.
