As noted by the previous reviewer, to get to the trail through YMCA, one has to be a member. However, there are other ways in. One "entrance" is at the back of the parking lot of one of the buildings in the adjacent Hawthorne business park (approx. coordinates: 33.968952,-83.418568). It's not an official entrance but it gets you onto the trail within a few feet.
Another entry is through the field behind Oglethorpe Elementary (33.965255,-83.424781).
(Since I don't know if the Y actually owns the trails/forest, I don't know if this is considered fully legal or not, your call).
I've only tried one small loop so far (maybe 10-15min at a not very fast pace) I enjoyed it and given that I live only minutes away from that trail, I'll likely use it frequently. For a trail inside the city, I think it's pretty decent.
