The major share of all groomed trails in the state during the winter are against wheeled vehicles, even atvs with track systems installed are not OK. There are local clubs who are developing their own trail systems, one such club exists in New Durham. Check out
www.newdurhamvalleyatvclub.com. ATVs are extremely destructive to groomed snowmobile trails, the ruts which they create once frozen are almost impossible to groom out. As a club officer for a snowmobile club I can say that none of the clubs in the seacoast area allow atv use on snowmobile trails, The Fremont Rec Trails is the only state trail in the area which atv use is permitted.
