Just south along the Presidential ridge, Monroe is a common side trip for those hiking the Mt Washington. It is also a quick sunset or sunrise trip for those staying at Lakes of the Clouds hut.
The quickest route is up the Ammonoosuc Ravine trail from the Marshfield Base of the cog railroad on the west of the ridge. From Pinkham Notch the most direct routes are over Boott Spur via the Boott Spur and Camel trails or through Tuckerman Ravine on the Tuckerman Ravine and Tuckerman Crossover.
