We had an amazing stay at the Edge Hill Hut. The views over Lake Taupo are spectacular, especially during the sunrise. The hut has everything you need (pantry, portable speaker, Netflix in case the weather is not good, heater, books etc...) and of course, the outdoor bathtub is pretty amazing. It is clean, quiet and we really felt alone up there. Don't forget warm clothes as it can be very windy and chill.
It is worth every penny, this hut really has something special :)
