The other reviews capture the Lighthouse Inlet Heritage Preserve very well. If you start on the beach side path instead of the old paved road, and if you go all the way around to the end of Rat Island (no longer an island to itself) and then back, that's near enough 4 miles - and 4 miles of sand is not like 4 miles of paths or sidewalks. The trek is great for combing, walking, running, and cycling. Shells are plentiful, and you might find some great driftwood or odd debris. The swimming here is often dangerous, with powerful rip currents, but if you're strong, enjoy. The sense of space here is amazing for Charleston, particularly away from the beaten paths on Rat along the Inlet. Even on the busiest holiday these beaches are relatively wide open, and all other times, you might see 20 people or less, sometimes no one. This preserve has been my most frequented and best place to get away from it all, walk/run, and take photos. See you there :)
