Rock n'rollin'! The most fun I've had driving on the worst, most rocky, rutty, bumpy, uneven road and through the river lots of times! What a hoot! My husband and I shared a side-by-side. My only regret was not giving him a chance to drive because it was sooo much fun, but, he admitted it was great even for the passenger! Great views once we stopped several different times. Lots of good info on the area, geology, and history. Definitely a Denali must do!
