The trails in College Woods are very well maintained. They are mostly flat and are non-technical in nature.

Riding in College Woods is a really fun experience, perfect on a hot sweaty summer day when the cool of the woods will provide you with a refreshing breeze as you ride beneath the dense forest cover. You'll find miles of rolling woods roads; some mostly smooth singletracks and you'll see lots of people out on the trails. Expect to loop around a lot. There are about 9 miles of trails, but to explore them all you'll have to do a lot of repeats.

The main water supply for the UNH campus is located in a dammed section of the Oyster River. A trail runs beside this reservoir and a newly constructed wooden bridge crosses it.

Directions:

From route 4 take Route 155A south towards Durham/UNH. Go right on College Road after 1.2 miles. Turn right on Colovos Road, go under the bridge and turn left. Park at the trailhead at the Waterworks Road intersection.

Cautions:

You will see a lot of people out on these trails. And a lot of unleashed dogs. Slow down, or stop, and say "Hi!".
