This national park is MASSIVE - 6.2 million acres, with over 2 million of those designated wilderness......larger than the state of New Hampshire! This is also the only national park set up specifically for the protection of wildlife (in particular the Dall Sheep). There is only one road in & that only goes 93 miles. You can drive the first 15 on your own, the rest you have to take a shuttle bus to. The 'big 5' animals in the park these days are those Dall Sheep, along with Moose, Caribou, Brown (Grizzly) Bears, and Wolfs. We managed to see everything but the wolfs. And we saw the mountain! Supposedly only 30% of visitors do, so we consider ourselves fortunate!
