Hathaways Pond is part of the Sandwich glacial moraine deposits. The route is a hilly mixture of wide, curving singletrack and walking trails. It sports several short but tricky rutted hardpack descents (or climbs if you're going the opposite direction). Roots abound, giving the quick, hilly singletrack a challenging flavor for novice mountain bikers.
The trailhead is just right of the parking area under some trees with a pet pooper scooper dispenser directly next to it. This network winds around the pond, branching off into several outer perimeter walking trails with outlets leading up towards Route 132. Be sure to keep right to avoid looping back around on these by accident. The main loop is short, maybe 20 minutes at most for an experienced rider. An added bonus is educational interpretive trail signage describing the area's glacial formation over 15,000 years ago. A handy companion trail guide for the Hathaways Pond Conservation Area is also available for download.
During the summer, be prepared to either buy a Barnstable beach sticker or pay a daily parking fee to come here. Bring a snack and/or lunch to enjoy the designated picnic area after an invigorating ride around the lake. As with all Cape Cod multi-use recreation areas, please respect the rights of others - especially runners, hikers and dog walkers.
Hunting is allowed in-season, so be sure to check the map kiosk for schedule info during the fall and winter months.
