Grand Teton National Park is definitely one of my top 10 favorite National Parks. It always amazes me how impressively the mountains come rising up right out of the valley floor.
As far as photography in Grand Teton, I spent most of my time there before I was really serious into photography, so I don't have too many photos to share. Hiking some of the canyons into the heart of the Tetons is on my short list of things to do, as well as getting one of those classic photos with the Snake River.
