On the Congaree River, this park is the largest portion of old-growth floodplain forest left in North America. Some of the trees are the tallest in the Eastern US, and the Boardwalk Loop is an elevated walkway through the swamp.
This trail actually had a mosquito meter and it's well worth it to check it out. This is a swamp so after a good rain it is wet and slippery. Beautiful flora and fauna and loads of wildlife. Feral hogs so keep an eye on your pups. Had one get completely out of her harness to have a look and we had to plough through muck to go get her. There is a boardwalk and a trail, in fact a few well marked trails and some are quite long. The boardwalk is no dogs allowed. We really enjoy this trail but it is clearly for hiking, not a breezy walk amongst the trees but have a look. It's well worth it.
I hiked this trail in June of 2016. You walk on the boardwalk, passing by bald cypress trees, tupelo trees and loblolly pine trees. It is a beautiful area.
Here is a short video I made of the pictures we took along the hike.
It's great that this area is protected but not exactly a scenic experience. Bottomland forest without much wildlife and no real views. If you like old growth hardwoods in the bottomland, this is the largest collection of that! If you don't know what that means, this trail will suck for you.
Li K. on Oakridge and Kingsnake Trails
Giant blue egrets (?), giant pileated woodpeckers, giant trees, not quite giant but pretty impressively sized hogs. Long flat trial, a little muddy.
Bill A. on Oakridge Trail
Flat, shady, muddy at times. Very frequent red blazes. Common to see wild boar. Check conditions before going as flooding is common in winter.
