Glowworm Caves

Deep in the rainforest near Haast, the Glowworm Caves offer an enchanting subterranean experience. As you step into the darkness, thousands of tiny bioluminescent glowworms create a starry ceiling above, casting a magical blue-green glow. The caves are part of a limestone system carved by the Te Waikoropupu River, and the guided tours share fascinating insights into the geology and ecology of this unique environment.

Highlights & What to See

• Glowworm Grotto: The main chamber where glowworms cling to the ceiling, resembling a miniature Milky Way.
• Limestone Formations: Stalactites, stalagmites, and flowstone created over thousands of years.
• Underground River: Listen to the gentle flow of the river that carved the cave system.
• Guided Tour: Knowledgeable guides explain the life cycle of glowworms and the cave's history.
• Nearby Rainforest Walks: Combine your visit with a walk through the lush West Coast rainforest.

Suggested Time to Spend

Allow about 1–1.5 hours for the guided cave tour. If you're self-driving, you can easily fit this into a half-day stop along the Haast Pass highway. For a more relaxed experience, combine it with a picnic lunch at the nearby Fantail Falls or a short hike in the area.
