Forest Closure Update - Monday, August 29, 2011
The White Mountain National Forest will remain closed until further notice. Forest Service personnel are currently verifying the conditions and stability of the roads, bridges, campgrounds, trails and other facilities on the Forest. Please be advised that road surfaces may appear stable but could give way under little weight. The Kancamagus Highway is closed. For additional State road conditions within the White Mountain region and statewide please view this link - http://www.nh.gov/readynh/index.htm
I'm sure you can still get to some of the trailheads, but I don't know how much they'll frown on that. Officially, the entire WMNF and all trailheads are closed until further notice.
