Yosemite, was the most breathtaking place I have experienced, you are surrounded by huge granite walls. Sadly Yosemite falls was not roaring water over the edge.
As it was summer. Death valley also blown me away, it was a stretching desert with a wide valley, surrounded by hills and mountains. It's highest temperature was 56 degrees Celsius. but it was only around 30-40, when I was there. Lake Tahoe, was awesome, it was cool to see a massive lake bigger than any lakes here in New Zealand. And it is also has a big elevation between it and the sea. America, jut blew me away, with its huge open plains, its amazing scenery, and the thrill being there.
