This is a beautiful cabin overlooking the lake and has been by far the best place we've stayed on our NZ trip so far. The view is simply stunning and we ate all our meals on the decking overlooking the vista.
A short walk down the hill (heading round the lake clockwise) there is a relatively secluded beach, 5 mins further along a woodland path is a larger beach. The other direction has a beautiful nature boardwalk where you'll see unbelievable nature including black swans!
