Willowdale is part of a massive network of doubletrack and singletracks plowing into the forests of Wenham and the surrounding towns. It networks together with Bradley Palmer State Forest, Georgetown-Rowley State Forest, and Willowdale itself. The trails themselves are a mix of rolling, smooth, and rooted single and doubletrack that makes FANTASTIC riding. Plenty of climbs and technical challenges can be found, but the real high-point is the well-maintained and marked trails that go for miles with countless singletrack shoot-offs that re-merge onto the double track. One of the best rides in Massachusetts! You could ride here every day for a month and not experience everything.
