If you have time you should take a trip into the park at Denali, even if you don't see the mountain you are sure to see some amazing sights. I spent 2 days hiking/camping there 2 years ago, saw the big mountain a few times but that paled in comparison to all the wildlife and other scenery. Went up on a plane from Talkeetna that was supposed to land on a glacier up on Denali but the cloud cover dropped too low, we still saw a lot of the lower glaciers, awesome sight from above. Weather is definitely unpredictable there, I was in snow on the 4th of July. I highly recommend a meal or 2 at the Roadhouse in Talkeetna, I stayed in a room there for a couple of nights, interesting place with lots of history and awesome food.
