Folly Beach is Emma's go-to beach in the area. There are many options for parking. There are areas for swimming, surfing, etc.
This is a fun way to see downtown Charleston. Find neat southern goods and trinkets by walking through the Charleston City Market. Emma encourages you to haggle for a deal (though she has not had luck with it).
Another activity for downtown Charleston. Walk through the park and take photos of the pineapple fountain.
Another beach option!
