The St. Marks trail is a 16 mile trail used by bikers, roll bladers, and walkers. This trail is a wonderful place to exercise. The trail is paved and wide enough to support a number of people.
There is plenty of parking at various spots on the trail so this trail is easy to access. Also, the St, Marks trail is dog friendly so feel free to bring your furry friends.
What I really like about this trail is that it is marked throughout so you know how many miles you have traveled.
