This was amazing. Extremely expensive at $650 pp but it was our honeymoon so we decided to based on a recommendation from a relative. Zero regrets. Big windows on the plane and you fly pretty close to the mountains on the way. Glaciers and hidden mountain lakes. Just stunning. Then Milford Sound itself with a boat cruise - just spectacular. Fantastic food on the boat and waterfall experience. If you splurge on one thing whilst you’re here then do this!!!
