Hwy 9

Hwy 9 information

Lonely Planet review

East of the main park entrance, Hwy 9 rises in a series of six tight switchbacks before the 1.1-mile Zion-Mt Carmel Tunnel, an engineering marvel constructed in the late 1920s. It then leads quickly into dramatically different terrain – a landscape of etched multicolor slickrock, culminating at the mountainous Checkerboard Mesa .
