Skip,
Try these two addresses, New Hampshire Bureau of Trails:
nhtrails@dred.state.nh.us and The New Hampshire Division of Parks and Recreation, :
nhparks@dred.state.nh.us , (603) 271-3556. They are the ones who would be negotiating with the Trust as to the Insurance issues and would there for know what trails would be open at the Castle? The Trust has a full time “Land use Coordinator” that we deal with directly here in Moultonboro and have had a very good working relationship this season.
