I visited Hilton Head a couple times with my family when I was a kid. Fond memories in Harbour Town visiting the lighthouse, eating ice cream, riding bikes, playing golf, and daily afternoon rain showers at 2:30pm. Check out the famous Salty Dog Cafe. I also went back for senior week in college between the week of finals and graduation. Most people made it back for graduation and were at least physically present. And who knew there was nightlife. I remember days on the beach and nights of frozen drinks and tiny shooter bottles. At the time at least bars were stocked with the tiny shooter bottles you get on airplanes instead of handles you typically see at bars everywhere else in the world.
Congaree National Park
Swamp forest free to visit for a short stopover if you need a break driving through the state. The boardwalk takes you through the swamp in a loop and you’ll get to see some interesting terrain, tall cypress trees, and pygmy trees in additional to some wildlife. Be warned the spring/summer brings nasty mosquitoes and deer flies, whose bites sounds quite painful like horse flies. If you wear bug repellent and/or long sleeves it’s no problem though.
