New Zealand
Emerald lakes glow in the craters of an active volcano on a moonscape ridge walk.
The emerald lakes sit in volcanic craters that last erupted in 2012. The Tongariro Alpine Crossing in New Zealand's central North Island traverses a landscape of active volcanoes, steaming vents, and crater lakes so green they look lit from below.
The 19.4-kilometre crossing takes six to eight hours and traverses three volcanic peaks — Tongariro, Ngāuruhoe, and the flanks of Ruapehu. Red Crater's rim steams underfoot, and the sulphurous smell intensifies as you descend to the Emerald Lakes. Ngāti Tūwharetoa gifted the peaks to New Zealand in 1887, creating the country's first national park and one of the earliest in the world. The weather on the volcanic plateau changes in minutes — clear skies can become whiteout within a single hour. The Department of Conservation rates this as one of the finest day walks on the planet.
Solo
The crossing rewards early starters who outpace the shuttles. Starting before dawn, alone on the volcano, with the landscape revealing itself as the light builds.
Couple
The shared effort of the climb and the shared silence at the Emerald Lakes create a day that becomes a relationship milestone.
Friends
The shuttle logistics, the pace negotiations, the group photos at Red Crater — this is the day hike that friend groups remember decades later.
