Waiheke tunnels

Highly recommended. Need good walking shoes - around 25 mins walk to tunnels and around 35 mins back to the car park. Definitely worth doing.

Amazing :)

Absolutely amazing. Definitely worth the money. They are doing an amazing job doing up all of the tunnels and chambers :) Just incase you've prebooked - The road to the place is 30mins long on gravel. There is about a 15min walk to the reception for the tunnel tour. 100% needs to be on your too list!!!
