A large area of over 6200 acres, I added the parking area to the map to help get you there. From 314A (SE 160th Ave in Ocala, Florida) it's just 7/10 of a mile down SE 137th Avenue Road to see the sign, and there is plenty of room to park your car or horse trailer. In fact, this seems a popular destination for horseback riding in Ocala.
The trail biking is also very good, with woods and small hills leading to Old Celery Farm Road, the bulk of Levee Trail. This trail road offers hard earth, no motor vehicle access, and great views of the Ocklawaha prairie. No doubt, the Saint Johns River Management District is doing good work here, restoring wetlands to a previous state.
I just can't recommend it for a hike, unless you are already in the neighborhood. I enjoyed my 6 miles, heard plenty of sandhill cranes in February, and a bridge over the Kyle Young Canal (mislabeled on Google Maps as the Ocklawaha River) leading to a view of the prairie are high points. But the trails seem to lead aimlessly without destination, and tend to just end either at a neighborhood, private property, or nowhere at all.
These aren't complaints. The restoration efforts serve bigger purposes. There are just more interesting place nearby to hike.
Bring your off-road bike or a horse, and have an enjoyable ride!
