Glowworm Caves

Deep beneath the lush rainforest of the West Coast, the Glowworm Caves near Franz Josef offer a magical subterranean experience. Guided tours take you into limestone caverns where thousands of tiny glowworms illuminate the darkness like a starry night sky. The gentle sound of dripping water and the ethereal blue-green glow create an unforgettable atmosphere.

Highlights & What to See

• Glowworm Grotto: The main chamber where the ceiling is covered in glowworms, resembling a celestial canopy.
• Limestone Formations: Intricate stalactites, stalagmites, and flowstones shaped over thousands of years.
• Underground Stream: A crystal-clear stream that winds through the cave, adding to the serene ambiance.
• Guided Tour: Knowledgeable guides share insights about the cave's geology and the glowworms' unique lifecycle.

Suggested Time to Spend

Allow around 1.5 to 2 hours for the guided cave tour. It's best to book in advance, especially during peak season. The caves are accessible year-round, and the tour operates in small groups to minimize impact. Pair this with a morning or afternoon exploring Franz Josef Glacier for a full day of West Coast wonders.
