Surreal experience, National Park perfection!
Drive alllll the way to the end of the road in Denali. As if you weren't already rewarded by the trip through the park, this campground is incredible. You can't choose a bad site, almost all of them have a view of Denali (assuming it doesn't hide in the clouds). So much wildlife! We saw bears along the road but no evidence of them near the campsite thanks to the rules in place (store food in lockers). Camp sites weren't close together, "neighbors" are from all over the world and fun to talk with.
Facilities are clean and among the best I've encountered in the National Park system. Tents only!! Make reservations far in advance.
Lots of hiking in the area or just bushwhack (check with rangers for policies). Once in a lifetime adventure, stay a few days!
