Run & Walk

45 km (28 miles) of trails surrounded by the beauty of the White Mountains

Free! No trail pass required for walking and running. Dogs welcome.

Rolling carriage roads and challenging single track through our woods makes Great Glen Trails a wonderful place to run and walk during spring, summer and fall. All our trails are clearly marked and can provide you and your family with a fun day of exploration.

Our trails are sometimes closed during mud season and for special events. Check the Hours of Operation.
