Wambaw Creek Wilderness
The 1,832-acre Wambaw Creek Wilderness surrounds and protects about 11 miles at the lower end of Wambaw Creek. Visiting the area requires a boat and use of a boat requires timing: the upper two miles of Wambaw Creek are usually blocked by logs but when the tide is in enough (or there's been enough heavy rainfall), the logs float and a boat can make its way through the morass. A journey on the creek will show that early pioneers tried to drain this swamp using levees, dikes and canals. However, due to the the proximity to the Atlantic Ocean and the relative lack of altitude, the creek bed is altered with every high tide. Wambaw Creek varies from 20 to 80 feet in width and harbors a few American alligators.
There are several Forest Service roads that come close to Wambaw Creek but there are no amenities of any sort. The only trail follows the ever-shifting creek, and it's a canoe trail. Bugs are heavy in spring, summer and fall. Summers are hot and very humid. Human traffic in the wilderness is very light, probably making Wambaw Creek Wilderness the second least visited spot in the state.
