Grand Teton National Park is so near to Yellowstone, but so frequently overlooked. The Tetons are captivating. They are the type of view where you see them and are forced to pull the car over to get out and look at their beauty.
During one two day period that we were there we saw 6-bears. There were three cubs running up a tree with their mother making sure that they were safe. You have to gain some elevation to get some of the views, but it is an astounding place. If you are in Yellowstone, don't make the mistake of not seeing Grand Teton
