Explore glowworm-lit caverns and tour New Zealand's second oldest building during this day of discovery. Bay of Islands' famous glowworms light a virtual universe of constellations in the darkness of limestone Kawiti Caves. Watch this remarkable natural phenomenon in silence that lets the creatures spin intricate masterpieces, then view this wonderland's stalactite and stalagmite formations. Tour ends with guided visit at historic Waimate Mission House, New Zealand’s oldest European-style farm where a treaty ensuring Maori rights was signed.
