The Chasm

A short scenic walk near Milford Sound featuring a natural rock amphitheatre carved by swirling waters and giant boulders. It's an easy accessible walk showcasing the raw geological forces that shaped Fiordland.

Things to do

• Walk the Chasm Loop Track — Follow the short, well-maintained loop trail descending to the natural rock amphitheatre carved by swirling waters over millennia.
• Photograph the Boulder Pool — Capture images of the dramatic swirling basin where giant boulders have been polished smooth by centuries of water erosion.
• Study Geological Formations — Examine the exposed rock faces and boulders to understand the erosive forces and geological history that shaped Fiordland's landscape.
• Listen to Water Dynamics — Stand at the chasm's edge and observe how water spirals through the narrow gorge, demonstrating the raw power of natural hydraulic forces.
• Explore Native Beech Forest — Walk through the surrounding temperate rainforest of silver and red beech trees endemic to this region of New Zealand.

Food to try

• Fresh Greenshell Mussels — Sample locally farmed mussels from Milford Sound, typically steamed or prepared at nearby lodges and cafes near the Chasm.
• Venison from Fiordland — Try slow-cooked venison dishes at Milford Sound accommodations, sourced from the region's managed deer herds.
• Fiordland Whitebait Fritters — Enjoy seasonal whitebait (tiny native fish) fried into delicate fritters, a Southland specialty available during the season.
• Pies from Local Bakeries — Purchase hearty meat or vegetarian pies from shops in Te Anau before your visit, ideal for picnicking near The Chasm.

Local customs & good to know

• Respect Māori Heritage — Acknowledge that Fiordland holds deep cultural significance to Ngāi Tahu iwi, and this landscape reflects thousands of years of Māori connection to the land.
• Check Weather and Tides — Always verify local weather conditions and water levels before visiting, as rapid changes in Fiordland are common and the chasm can become unsafe during heavy rain or high water flow.
• Stay on Marked Trails — Adhere strictly to the designated track, as the terrain around the chasm is slippery and unstable, and rockfalls are a genuine hazard in this geological environment.
• Leave No Trace — Pack out all rubbish and avoid touching or climbing on the boulders unnecessarily, preserving this delicate natural wonder for future visitors.
