This is a guide to the Terrifying 25 list of the most frightening trails in the White mountains. There are steep slides, exciting scrambles, and other aspects that may petrify hikers. There are twenty trails that must be completed and ten optional trails of which you must complete five. Although I've only just started this list, I've had lots of fun so far and can't wait to do more of them. i'll be sure to update this page as I go!
