Description below from Liberty Bike Trail web site :
The Liberty Rail Trail runs approximately 3 miles. It is easy to get to as there are 4 entrances to the trail. The trail is made up of 3 different sections.
To experience the full trail, you can park on chestnut street and enter the trail after going over a vintage stone bridge. From this point you can ride or walk the entire trail from Spur Street to the old trestle in Ferndale.
Part of the trail is now road, but it is not busy. From behind Agway to the entrance at the end of State Street you have to travel on the side of the road wich was once railroad bed.
Please use caution while crossing Lake Street in the center of the Trail.
