Open sugar house at Great Mountain Forest. If the weather is right, sap will be boiling and visitors are welcome to come find out how it’s done. Afterward, you can enjoy the trails on foot, snowshoes or skis. Both the sugar house and the trailhead are next to the GMF forestry offices at the end of Windrow Road. If the weather has not cooperated with warm days and cold nights to get the maple sap flowing, the open sugar house will be canceled but trails will still be open. You can call the forestry office (860-542-5422) the preceding week to check on this event.
