43.5 km

Duration

3–4 days

Country

New Zealand (NZ)

Difficulty

Moderate to strenuous — circling an active volcano, lava rock terrain, altitude above 1,800 m, and the rapidly changing weather of the North Island

Best Season

Late October–April (DOC Great Walks season); May–October the trail is open without mandatory booking, but the huts do not operate fully

Permits & Fees

DOC hut reservations are mandatory during the Great Walks season (Mangatepopo Hut, Ketetahi Hut, Waihohonu Hut) — booking opens online around October each year and fills quickly. 2026 note: the Ketetahi section is still recovering after the 2025 fire, reducing the trek distance to about 35.5 km; check the latest status on the DOC website before departing.

Description

The Tongariro Northern Circuit is New Zealand's second-longest Great Walk and the only one routed entirely across an active volcano — a 43.5 km loop circling the summit of Mount Tongariro in the heart of Tongariro National Park on the North Island. The 3–4 day trek traverses a surreal volcanic landscape: the still-steaming rim of Red Crater (1,886 m), the mineral-coloured Emerald Lakes below, the vast barren expanse of South Crater, then down through lush Waihohonu Valley. The route incorporates a section of the famous Tongariro Alpine Crossing, widely considered one of the best one-day hikes in the world. DOC hut bookings are fiercely competitive. Mount Ngauruhoe, visible throughout, is famous worldwide as the filming location for Mount Doom in the Lord of the Rings trilogy.

Trail Highlights

Red Crater (1,886 m, the highest point of any Great Walk in New Zealand), the Emerald Lakes turquoise from sulfur deposits, Blue Lake (a sacred/tapu Māori lake), panoramic views of Mount Ngauruhoe and Mount Ruapehu, the barren Mars-like landscape of South Crater, and the Upper Tongariro Valley. Tongariro National Park is a dual UNESCO World Heritage Site — recognized for both its natural value and its Māori cultural value.
