Great for all ages and skill levels. Handicapped accessible and beautiful views.
Very quiet, road biking trail. I think it was a rail track that was paved, and they are continuing expansion of the trail. It was very flat, lots of trees that provided shade, and lots of other bikers/joggers/roller-bladers. The scenery was absolutely beautiful too. I really enjoyed it, this site says it's 11 miles, but I traced it on google maps and it turned out to be 18 miles, the difference may be due to the expansion. But over-all, a great ride!
