These trails obviously lack of maintenance, the trails are covered with knee-high grasses. We walked the Little Back River trail on rough grasses for half a mile before deciding to turn back and drive on to Tupelo trail. We were able to walk a mile then the trail's condition turns to the same. We finally agreed to quit with disappointment.
Visitor center are very nice, the entrance from 17 is fully equipped with the electric gate, ten of cars park in the staff parking lot, the county seems to invest more in visitor facility and staff than maintaining the hiking trails.
I do not recommend to hike over here.
There are many miles that one can run at the reserve. Some trails are paved with crusher run and wide enough for a truck to drive on them (no cars/trucks allowed) and some trail are just grass and dirt. Very flat, very scenic lots of wildlife and mainly alligators. Running on the gravel was ok but the grass was kind of tall (un-cut) and the snakes plentiful! I would recommend staying on the gravel! Very little shade as there are hardly any trees on the trails.
