Nice trail. I think I've ridden the whole thing in a couple of visits. My favorite part is the Fanning Springs to Chiefland. Last time I was there I did a triangle shaped route between Fanning Springs – Chiefland – Trenton (had to go off trail) then back on the trail again until I got off to go to Manatee Springs. It was a crazy hot day in the middle of summer and it felt really good to swim in the spring. I’m returning next month. The weather should be much improved.
One odd thing I saw the locals do is ride their bikes on the trail against “traffic”. It was a little disconcerting.
