Peru
Pastoruri Glacier
Walking on a tropical glacier — ice underfoot at 5,000 metres beneath an equatorial sun.
Ice crunches beneath your boots at 5,000 metres, the sun directly overhead and hot on your neck. The contradiction is physical — equatorial warmth above, glacial cold below, the air so thin each breath feels like drinking through a straw. Interpretive markers along the trail show where the ice edge stood last year, the year before, the decade before. The glacier is retreating in real time.
Pastoruri is a tropical glacier in Peru's Áncash region, inside Huascarán National Park — one of the few places on Earth where you can walk on permanent ice beneath an equatorial sun. The three-hour drive from Huaraz gains 3,000 metres of altitude, passing herds of vicuña on the approach. The glacier has retreated approximately 700 metres since 1980, and interpretive posts along the trail mark each year's ice edge, turning the walk into a visible record of climate change. Puya raimondi — the world's tallest flowering plant, blooming once after decades of growth — can be seen en route. The combination of tropical glacier, high-altitude wildlife, and dramatic botanical oddities makes Pastoruri a single-day experience of extraordinary range.
Solo
The walk is meditative and sobering — pacing the retreat markers alone, feeling the altitude thin your breathing, watching a glacier that may not survive the century. It rewards the reflective solo traveller.
Friends
The altitude challenge creates natural camaraderie. Walking on tropical ice together, spotting vicuña on the drive, and recovering with huallpa chupe in Cátac makes for a shareable adventure day from Huaraz.
- Pastoruri is a tropical glacier at 5,240 metres — one of the very few places on Earth where you can walk on permanent ice beneath an equatorial sun.
- Access from Huaraz takes 3 hours by road through Huascarán National Park, gaining 3,000 metres of altitude past herds of vicuña.
- The glacier has retreated approximately 700 metres since 1980 — interpretive posts along the trail mark each year's ice edge, the recession visible in a single walk.
- Yellow-throated pikas — small high-altitude mammals — are often seen near the glacier edge, darting between rocks in the cold thin air.
Huallpa chupe — chicken chowder — at Cátac lodges after the glacier, thick enough to restore body heat.
