Yes, lots of people were when we went.
Yes most of the trails are very good for cycling. I’d go slowly and quietly or you’ll miss the best part which the wild life.
Yes, however, I would go earlier rather than later. The trails, especially on weekends, get a bit busy around certain areas. You may need to wait behind people who are walking (near the dock - I think that is called Rabbit Run) or if a group gathers near an alligator or the momma pig and her babies (Heron Hideout as of late).
The back trails are much easier to get around and fewer people. Have fun! It is beautiful!
Yes...definitely....perfect way to tour the area....
