I was up there in early January and they were grooming then. Go to the Lake Gogebic Chamber of Commerce page for a trail report. They are out grooming!
They've been grooming most trails all year with the exception of a cpl( 8 & 102 I believe), with the amount of traffic up there they can only do so much. Earlier the better for the smoothest trails around the lake. Have fun & ride safe!
Trails near Bergland we're really beat up yesterday as there was a ton of sleds up here and the temps were warm. Groomers were out doing the best they could but a half hour later you would have never known a groomer had gone through. Need some colder weather
