Privately owned but very open to the public. Wow, this is really nice. The loop trail ( over a mile in length) encompasses the perimeter of the school campus. The terrain is 30% hills (some very steep, but short) and 70% flat. The staff at the school take excellent care of this wood-chip path. The path also goes right by the school's first rate track (also open to the public).
This is a great facility. TRAIL PHOTOS
Directions: From Atlanta take Ga 400 north and then go east on I-285. Take the first exit (Ashford-Dunwoody Rd) and turn right (go inside the perimeter). Marist High School is about a mile down the road on the right.
Special events: The school hosts a road race once a year. I do not have any details but please let me know if you do.
