Tour of Tewksbury is a 17.7 mile loop trail located near Oldwick, NJ and is rated as moderate. The trail is primarily used for road biking and is accessible from March until November.
Just a note of warning. The directions to this TH takes you to a residence and NO TH. Never did find it. If you don't know where it is I would pass on this one
My wife and I rode the Columbia Trail from High Bridge to Schooleys Mountain. 13 miles each way. Trail is well kept, it is slightly uphill going North but it is easier coming back.
Scenery is beautiful, and it is shade most of the way.
