This is an excellent hike. I live nearby and I hike it all the time with my dog. The map however is no longer accurate. If you are on the northern section, returning from east to west, the dashed line in the middle (currently shows the number 5 in red below the track) is the actual trail. The sharp right turn shown may have been a trail at one time but it is no longer there. I tried to trace it but it petered out within 100 meters. This means that the easternmost section of the trail actually a lollipop, bringing you back to have to walk at least a short section that you have already been on. If you are at the junction that is the western end of dashed line connecting trail (which "should" be a solid red line) there is another junction about 215 meters to the west that is clearly marked as on the "3 Mile Loop". Go north on this and it will take you back to the northern section of the trail. The good news is that, when you come to where the false turn is, the trail is clearly marked. Just follow the orange blazes and the sign that says "Hiking Trail". I hope this hasn't confused anyone.
I live in area, so use this trail a lot. Most hiking I do is out West and my 4 star rating is very relative to the area. This is a really nice paved trail for cyclists, walkers, joggers, rollerbladers, etc. This park goes through the sandy palmetto woods in this part of Florida. I saw probably 20 gophers today and have seen snakes a few times on the trail. It's a great trail for cyclists but okay for hiking, just extremely hot from May to November.
