It does get busy with families with baby carriages on the weekends. The only thing I hate about it are the dog owners who allow their dogs to run free. Other than that the park is decent. Good begginer terrain. Start with the main trails before heading off to the woods.
Experienced riders can just head for the single track in the woods.
The trails are not very difficult and there are lots of families on weekends. Look up near the actual falls and along the river for the more difficult terrain. There is a good loop around the lake too. The mapped routes are wide, flat, and fast. From the parking area off of Simon St, take a left after the bridge and stay left past the Rt 3 overpass.
