Quabbin Reservoir Gate 43 Circuit

Gate 43 opens onto a network of gravel roads threading through the drowned Swift River Valley, where four entire towns were sacrificed to create Boston’s water supply in the 1930s. The main route follows old Route 21 past stone foundations, cemetery remnants, and the famous Quabbin Tower, while side spurs lead to cellar holes in Dana and Prescott. Wildlife is abundant—moose, bear, and the largest bald eagle population in Massachusetts call this 39-square-mile wilderness home.

Easy to moderate depending on recent weather and maintenance. Most routes are well-maintained gravel suitable for any vehicle with decent ground clearance, though some side roads require 4WD. Open year-round with seasonal restrictions during hunting seasons. Camping is prohibited, but the area offers world-class wildlife viewing and photography opportunities. Bring plenty of water—ironically, drinking from the reservoir is forbidden despite containing some of the cleanest water in New England.
