On the ride from the park entrance, the best place to sit in on the left hand side of the bus (another way to say this is to sit on the same side of the bus as the driver). This gives you the best views of Denali. It also gives you views of the drop-offs on the cliff section of Sable Pass and Polychrome Pass (so if you are afraid of heights and there’s room, pop over to the right side of the bus for this section, or close your eyes).
