    • There are three access routes to Ruapehu, leading to three skifields: Whakapapa, Turoa, and Tukino.

    Crater Lake and Eruptions

    • Crater Lake is situated at the southern end of the Summit Plateau and is filled with a warm, acidic lake.
    • The lake's outlet is at the head of the Whangaehu Valley, where the Whangaehu River arises.
    • Eruptions have built tephra dams across the outlet on several occasions, causing destructive lahars down the river.

    Glaciers

    • A total of 18 glaciers have been recognized on Ruapehu, with six named glaciers.
    • Two glaciers are found in the active crater, and most of the ice on Ruapehu is contained in the Whangaehu, Summit Plateau, and Mangatoetoenui glaciers.

    Climate

    • Mount Ruapehu has a polar tundra climate (Köppen: ET) on the upper slopes.
    • The glaciers are sensitive to changes in climate and have been thinning and retreating since 1955, with the exception of the northern crater glacier.
