Hiking up to Key Summit offers a breathtaking alpine experience that showcases the grand scale of the Fiordland wilderness. The trail branches off the world-renowned Milford Track, climbing steadily through a spectacular, moss-draped silver beech forest before opening up onto a windswept alpine plateau. At the summit, a self-guided nature walk leads you through unique alpine wetlands and tarns, offering panoramic views of three surrounding valleys.
Standing at the top, you are treated to dramatic, postcard-perfect views of the snow-capped Humboldt and Darren Mountain ranges.
One fun fact people love:
Key Summit sits on a major continental divide; rain falling on this peak can flow into three different rivers, ending up in either the Tasman Sea or the southern Pacific Ocean.

Commute difficulty:
Moderate; a well-graded gravel path with a steady uphill climb that requires comfortable walking shoes and average fitness.
Things nobody tells you about this place:
- The summit is incredibly exposed to alpine winds, meaning it can feel up to 10 degrees colder than the forest below; pack a windproof jacket.
- On a cloudy day, the summit can be completely swallowed by mist, leaving you with zero visibility, so check the weather forecast at Te Anau before hiking.
- The small alpine lakes (tarns) at the summit act as perfect natural mirrors for photographing the surrounding snow peaks.
