Just not in a snowstorm, in the middle of the winter in New Hampshire! Seriously, don’t do that, you probably will not make it home alive. In fact even if it is 70 degrees at the base of a 3000+ foot mountain in New England you should get a weather report at the top and should have a second layer of clothing ready just in case. It can go from 60 to 0 in a flash and you can be in a tough spot! If you are not experienced than wait until late April or early May to even consider doing a hike that is labeled above “Easy/Low Intermediate”.
Here are some of great hiking informational websites or posts about hiking in New England:
