Zion National Park
Here lie deep canyons, silent about the secrets they may hold, in the depths of land that was inhabited 11,000 years ago by indigenous peoples. Staggering cliffs hover above the Virgin River (you can swim in this water, but it’s cold). The hiking trail through the Zion Narrows is watery; partly a wading trail.
Zion National Park in southwest Utah is accessible because of a 1909 feat of engineering. A road had to be put through to connect the park to the Grand Canyon and Bryce Canyon; this was achieved, partly by tunnelling, and the 40km (25mi) road is used by thousands of visitors every year. The Zion-Mt. Carmel tunnel, when traversed, opens onto a natural scene like no other at the opposite end.
This is a favourite park for hiking (be wary of marked danger spots) and camping; be sure to visit the Emerald Pools and their waterfalls, resplendent with a hanging garden.
