If you want to get away from it all, this is the spot, you get a very modern house in the middle of the mountains. It's a 5km gravel road (we did it in a small Honda Civic) which is slow going but a day did not go by that we did not see an animal that we had not seen.
The house was super clean and although you can see your 2 neighbours they are a long way away.
The internet is spoty but if you are going for a trip like this internet is not the key, just make sure you plan before you go. There is a selection of DVD's there if you fancy watching something or curl up in the Hammock on the deck, there is also a BBQ. You are asked not to use chemical soaps which initially concerned us but when we arrive there was everything you needed.
There are no local shops (Middle of nowhere after all), you will need to drive 20 mins to Waipu where you can get everything you need, there are some great beaches and restaurants to enjoy.
The best part of this location, is that you are a 2 minute walk from Waipu Caves, they are just stunning, make sure to bring a good touch (spare batteries to be safe) and your sense of adventure, my 6 year old loved it so it can be done by families.
Only issue I had (maybe because I am a city boy), there were no curtains, it did not bother me apart from the sun in the mornings, I had eye mask so not the end of the world.
