The Chasm Walk

Plunging into a narrow gorge carved by the wild Waiho River, The Chasm Walk is a short, unforgettable detour near Franz Josef Glacier. The roar of water intensifies as you follow the boardwalk through lush rainforest, culminating at a viewing platform perched above a dramatic chasm where the river thunders through smooth rock formations. It’s a raw, sensory hit of New Zealand’s West Coast power.

Highlights & What to See

• The Chasm itself – peer into the deep, swirling cauldron where the river funnels through a narrow slot canyon; the force of the water is mesmerising.
• Boardwalk through temperate rainforest – spot ferns, mosses, and rimu trees as you walk; the air smells of damp earth and foliage.
• Multiple viewing platforms – get different angles of the chasm, including a close-up view of the water’s raw energy.
• Interpretive signs – learn about the geological forces that shaped the gorge and the surrounding glacier landscape.
• Nearby Franz Josef Glacier – combine the walk with a visit to the glacier’s terminal face or a guided ice hike for a full day of West Coast wonders.

Suggested Time to Spend

Allow 30–45 minutes for the return walk and time on the platforms. It’s a perfect short stop if you’re driving the West Coast – easy to fit in before or after a glacier excursion. Visit early or late in the day to avoid crowds and enjoy the light filtering through the canopy.
