Common questions

Are these trails hard?
Yes, riders and hikers alike describe the singletrack as tight, rocky, and rooty, rated difficult rather than a casual stroll.
Where do I park, is it obvious?
Not really. Parking is informal roadside space along Rayburn Drive at the power lines, and it's easy to miss on a first visit.
Can I bring my dog to Colton Conservation Area?
A Millbury dog owner must keep the dog under restraint at all times, and off the owner's own property the dog must be on a leash of six feet or less or under the owner's full control.
