If you're over on Waiheke, Stony Batter is an awesome day trip. It's on the eastern end of the island so you'll need a car to get there (about 40mins from the wharf the ferry arrives into). Stony Batter is a series of underground tunnels and rooms from World War II; if you are claustrophobic this is not for you! It's very very dark down there and the tunnels go pretty deep, so for everyone else it's awesome fun. A torch is ABSOLUTLEY ESSENTIAL, with out a torch don't even bother entering, it's dangerous. If you've forgotten yours you can hire them there for $5. This is where my highlight comes in; the lady you pay has a giant pet sheep. It follows her everywhere (I can't remember the name, but something like Dolly perhaps?). Anyway it's pretty bizarre to see this big woolly creature following her around like a dog; that alone names the trip worth it. read more
