Take I495 to exit 17 and go west towards Bolton Center. Drive approximately 2 1/2 miles and then turn left onto Forbush Mill Road. The Forbush Mill Fields parking lot is just under a mile from the turn, on your left.
The routes for this ride are the two hilliest loops of the celebrated Climb to the Clouds. Starting in Bolton, both routes go through the lovely towns of Lancaster, Sterling, Princeton, West Boylston, Boylston and Berlin. The 58-mile route includes a spin up to the top of Mt. Wachusett with a 360-degree view as your reward for the climb. The 48-mile route avoids Mt. Wachusett, but still provides some good climbing and screaming downhills. These are challenging routes and not for beginners. There is no registration required and the ride is not supported, but there are several places to purchase food and water along both routes.
If you require a cue sheet, please print it out and bring it with you.
