USA – Southwest

Texas
The second biggest state is like a separate country (and indeed once was), with strong cultural influences from its Spanish and Mexican past. The terrain is quite varied, with swamplands in the southeast, flat land and cotton farms in the South Plains, sandy beaches in South Texas and mountains and deserts in far West Texas.

Southwest (Arizona, Nevada, New Mexico, Utah)
Heavily influenced by Spanish, Mexican and Native American cultures, this area is home to some of the nation’s most spectacular natural attractions and flourishing artistic communities. Although mostly empty, the region’s deserts contain some big cities.

Rocky Mountains (Colorado, Idaho, Montana, Wyoming)
The spectacular snow-covered Rockies offer hiking, rafting, excellent skiing, deserts, and some large cities.
