The only animals I have seen along the trail are deer, armadillos, rabbits and birds. I'm sure there are some snakes in the woods, but I haven't seen them. I usually stick to the paved trail though. The other trail was pretty sandy the one time I tried it, and I hate getting sand in my shoes.
If you turn left at the bus stop and follow the sidewalk, you will come to a road first, and then you will see the paved walkway on the other side of the road. It's about a mile and it's not lit at night, so make sure you give yourself enough time to get all the way across if it's late in the day. We used to walk just before sunset because that's when the deer would be out. We would take the boat to FW and walk back.
