This is the classic and ultra expensive road trip. Most tourists I talk to are doing a route similar to this. I've altered it to avoid Anchorage as much as possible and include some other rich and fun things to do. And slows it down a bit so you don't feel rushed.
This trip starts and ends in Anchorage. You'll check out Denali, Prince William Sound, Kenai Fjords, and Kachemak Bay.
