Pros & cons

PROS

  • Easy 15–20 minute detour from Iris Burn Hut
  • Refreshing swimming hole at the base

CONS

  • Sandflies can be intense
  • No facilities at the falls

Overview

A short, rewarding side trip off the Kepler Track, Iris Burn Falls is the track’s standout waterfall—set in lush beech forest and reached by an easy 15–20 minute walk from Iris Burn Hut. It’s a graceful horsetail cascade in a tranquil glacial valley, and a favorite wind‑down spot for trampers overnighting at the hut.

What Makes It Special

  • The only significant waterfall on the Kepler Track, so it feels like a proper “destination” between big alpine sections.
  • A clear pool at the base invites a bracing dip after a long day.
  • Classic Fiordland atmosphere: mossy forest, dripping cliffs, and the hush of a secluded valley.

Getting There

From Iris Burn Hut (and the adjacent campsite), follow the well‑marked track to the falls—flat, quick, and doable even with tired legs. There’s no road access; you’ll be here only if you’re tramping the Kepler Track.

Wildlife & Environment

Expect lively native birdlife in the forest (think fantails and robins; kaka are possible but less commonly reported). Do expect sandflies—bring strong repellent and cover up if you want to linger.

Swimming & Safety

The pool is suitable for a quick swim in settled conditions, especially in summer. Rock and timber surfaces can be slick after rain, and Fiordland weather turns fast—pack rain layers and mind your footing. The descent into the Iris Burn valley on the track can be steep and slippery in poor weather; take care on approach days.

What to Bring

  • Insect repellent, rain gear, and sturdy footwear
  • Swimwear and a small towel if you fancy a dip
  • Camera—this one’s photogenic in all moods

Best Time to Visit

  • Evening or early morning from the hut: softer light, fewer people, and calmer air for photos.
  • After rain the flow is fuller (also slicker underfoot). Summer is best for swimming. Crowds are naturally limited since access requires tramping the Great Walk.

Good to Know

There are no facilities at the falls themselves. Toilets, water, and shelter are at Iris Burn Hut/Campsite a short walk away. The Kepler Track (opened in 1988 and managed by DOC) operates on a seasonal booking system—plan your itinerary around hut/campsite availability.
