Congaree is about 14 miles outside of Columbia, SC, in a cypress swamp with a river running through it. I was flying to Philadelphia for a high school reunion and thought I would go by way of Charlotte. From there, it is a couple of hours to Columbia, and a short hop to the park. When flooded, the boardwalks are the only way around, and some of them are flooded as well. I was there in late November, and everything was dry. There are a nice set of trails, and I spent the morning and early afternoon hiking. Saw some wild boar and some really large cypress trees. It’s a nice place, near a city but still wild.
