Spelunkers (cavers) say that New Zealand has some of the most challenging and spectacular caving systems in the world, but even first-time cavers can enjoy our underground scenery. Caving experiences range from a dreamy drift through a glow-worm grotto to a rip-roaring, rope-dangling, action-packed subterranean adventure.
The South Island has several caving areas - you’ll find guided underground adventures in Nelson, Fiordland and on the West Coast. Harwood’s Hole, just off the main Motueka-Takaka road in the Nelson region, is the deepest sinkhole in the southern hemisphere. You can look into it, but be careful you don’t fall in - it’s 180 metres straight down.
