Enjoy mile upon mile of picturesque Hunterdon farmland as you travel toward the Green Sergeant's Covered Bridge, the only remaining covered bridge in New Jersey. The route offers three different loops: 15, 24 or 48 miles long. The two shorter loops begin near Ringoes. The best parking for this route can be found at the Municipal Building located at Wertsville Road and Route 202.The long loop can begin at either Ringoes or Princeton. The entire route is hilly (especially the long loop) and for the most part utilizes low traffic volume rural roads traversing picturesque countryside. It should be particularly attractive when the leaves change color in the fall. Of the full loop, 12 miles wind through the serene woods of the Sourland Mountain Reservation. The ride offers a beautiful day away from civilization. Be sure to bring enough supplies along with you if you choose to do the full route.
At mile 7.5, you will come to the Green Sergeant’s Covered Bridge, the last covered bridge in New Jersey. You won’t ride through the bridge. Instead, you will make a left and ride along the creek on a very quiet road. Look up occasionally and you might see eagles, hawks and/or herons.
Please consider getting off your bike and walking across Route 31 at the corner of Rocktown Road and Route 31. This is a difficult crossing, but well worth it as it brings you to the other side of the mountain area. At the corner of Rocktown Road and Mountain Avenue, there is an alpaca farm.
If you need to refuel, at mile 24.5 you can take a detour onto Pennington-Hopewell Road that changes to W. Broad Street, Hopewell. Sourland Cycles is the local bicycle shop.
