US 20, the Wind River Canyon Scenic Byway, packs a scenic wallop: lofty mountains, clear blue water, canyon walls so tall they dwarf a skyscraper. This short drive offers history (it borders the Wind River Indian Reservation) as well as geology (the rock formations here are among the planet’s oldest). It’s a spectacular setting for fly-fishing and white-water rafting.
