The route is not well marked....or marked at all really. Basically you just ride to the bottom of Nassau road where it meets Washington Ave. Cross Washington and there is a trail right there that you cant see well from the road (greenway trail). Follow trail which should have you crossing over the river before you get 100 yards or so in. After crossing the river make a right into the lawn before a spooky looking old abandoned house. Ride to the back of the lawn where the trail continues going uphill for about another 100 yards or so and meets the Columbia trail. Go left on the Columbia trail and follow to the end where it crosses main street and hits the trail head parking lot.
