I have visited Wanaka many times and I think it is the most beautiful of New Zealand's southern lakes and Rippon enjoys the best view of this very special location.
Comments on Tripadvisor in 2013 and early 2014 could not be further from our experience. The kiwi lady who greeted us was incredible warm and very knowledgeable. She offered my wife and I a picnic blanket so we could find our own spot to leisurely take-in one of the truly great views of New Zealand's South Island (which is now my screensaver at my office in London).
We visited some spectacular vineyards in the South Island including Neudorf and Woolaston in Moutere (Nelson) and Amisfield in Queenstown. All of these places are worth a visit but our winner for the best cellar door was Rippon.
Thanks for such a great experience, you may have convinced my English wife to one day return to NZ! One day...
