Phinizy Swamp Nature Park is a 1,100 acre preserve located in the Industrial area of southeast Augusta. This free, open to the public, park is a learning center for water sciences and a popular event space. There are several miles of dirt roads, sandy trails, and boardwalks. The main loop around the park is a solid 7.7 miles, but there are plenty of shorter options too. The terrain is quite open, so use caution on a hot day.
This is one of the closest options to Augusta Regional Airport.
