The Seth Warner Shelter (LT mile 2.8 NB) will be deconstructed and permanently closed beginning 8/22/22. Please do not tent at this site after this date to allow for revegetation. A new shelter is being built 2.5 miles north, to be completed later this fall. In the meantime, you can plan to overnight at Sherman Brook Campsite in Mass; Congdon Shelter (~7 miles north of Seth Warner), or follow dispersed camping guidelines for the Green Mountain National Forest.
