El Chepe

Pass through 86 tunnels and over 37 bridges on this 11-day journey to the bottom of Copper Canyon in Mexico. The canyon is 400 feet deeper than the Grand Canyon. This train, known as the Chihuahua al Pacifico Railroad (as well as El Chepe), travels between the towns of Los Mochis and Creel in the state of Chihuahua. Evenings are spent in hotels. If you travel first-class, you'll have access to a dining car. If you travel second-class, you can buy snacks. The train climbs 8,000 feet above sea level near the town of Divisadero. One stop is in Creel, where, if you haven't had enough of a thrill already, you can go to an adventure park and take a tram ride.

$3,190: Per person, based on double occupancy. Round-trip airfare from Los Angeles, Phoenix or El Paso included -- www.calnative.com
