This is my FAVOURITE tourist experience to do in Queenstown!
It combines a trip on the beautiful, 110 year old TSS Earnslaw across lake Wakatipu with insane views of the mountains surrounding the lake. Then you arrive at Walter Peak, a high country farm with beautiful gardens and farm animals before heading back to Queenstown on the boat.
There are a few tour options to choose from but I would recommend the boat trip + farm tour, or if you have the budget and time add on the lunch buffet, the food is crazy good! I would not recommend the boat trip on it's own, getting away from other tourists and exploring the farm and it's views were my favourite part.
