There are three snow capped peaks within the national park, all of which are active volcanoes. I have witnessed on several occasions smoke, ash and lava spewing from various vents on the mountains, particularly Mt.Ngauruhoe. The crater lake on the summit of Mount Ruapehu periodically overflows, tipping its contents of hot water down its slopes.

Despite these hazards, in the summer the mountains are used by trampers following the various trails marked out on the landscape. In the winter it is a mecca for ski fanatics, with chair lifts and rope tows heading off in all directions.

There is a plethora of lodges on Mount Ruapehu, as well as at its foot. The area can be reached by rail services from Auckland and Wellington
