Not everyone has such a gem right in their back yard practically, and yet right here in Peachtree City at the county line is one of the area's most beautiful recreation areas. The trail at Line Creek Nature Area is the main attraction ad begins from the Northern trail head in an hardwood forested area heading towards the creek from the parking area towards granite outcroppings, and even some areas where the creak runs fairly swift over the rocks creating a pleasant sound as you walk nearby. The trail bordered by some ferns, various ivy like plants and azaleas.
This hike is a pleasant one of a little over a mile each direction. At the Northern part of the park, you will encounter a bit more terrain including rocks, and tree roots. I'd recommend good outdoor hiking shoes for this area and a few folks I encountered on the trail this morning had their own walking sticks. Be aware that you are out in nature and you might encounter snakes because you are near water. I didn't see any however, but I tried to stay aware especially around the bridges over drainage areas and washes.
The trail continues South until the creek runs into McIntosh Lake's Northern end offering up some beautiful views. Line Creek Nature area is owned by the City of Peachtree City and managed by the Southern Conservation Trust https://sctlandtrust.org/
and is located off of the Newnan - Peachtree Highway (State Route 54) with parking access to the West of the Shopping Center where T.J. Maxx is located. The Nature area is a beautiful place to visit and if you enjoy rigorous hikes that aren't too long amongst great outdoor scenery and nature, this is your place!
