Big Bend National Park

Rank: 143

Park Description

There is a place in Far West Texas where night skies are dark as coal and rivers carve temple-like canyons in ancient limestone. Here, at the end of the road, hundreds of bird species take refuge in a solitary mountain range surrounded by weather-beaten desert. Tenacious cactus bloom in sublime southwestern sun, and diversity of species is the best in the country. This magical place is Big Bend.
