Echoing what fatdad said. The road to the top is still closed. I rode up to the visitors center back on Labor Day, which is still a nice little climb.
If you're looking for a fun loop, you can start at the Wachusett Reservoir, take Route 110 to Route 12 into Sterling (near the airport), then take Route 140 all the way to Wachusett Mountain. After descending off the mountain you take Route 31 back to 62, which should get you in the area of the Reservoir. This is a very rough description of my Labor Day ride. Sorry I don't have a cue sheet.
