Haleakalā is like this as well. Don't just drive up the crater - hike through the thing. It's a ~12 mile hike. It's a remarkable experience because the landscape changes so frequently and dramatically from desert to tropical forest.

The only comp to this is like the transition in Max Max from the desert to the oasis.

Tourists that drive to the crater, take pictures, and drive down have no idea what they're missing.
