I love finding all the little hiking trails that are hidden all around the city. This City of Atlanta park has over a mile of hiking trails. It also has a playground and exercise equipment that were added in early 2013. There are some interesting areas along the trail, but I'll leave the details of those for you to explore yourself.
You can find the cache about 15 paces off the trail. It's on the small side for a small, but it does have space for a few small items.
City of Atlanta parks are open from 6:00 a.m. until 11:00 p.m. daily.
