Where do I park, and is it obvious?
There's a small gravel pullout at Notch Road near Reservoir Road; it's easy to miss and the surface is loose and uneven, so go slow if you're driving a low-clearance car.
Can I bring my dog to Bellows Pipe Trailhead?
Allowed caged, bridled, or on a leash or tether no longer than ten feet, unless an area is posted otherwise; never unattended or at large, and waste must be carried out. Hunting, hunting-dog training, dog sledding, sled-dog training and search-dog training are excepted (302 CMR 12.13).
