True—you have to be pretty confident to call your train the Palace on Wheels . But step aboard and you'll see this royal moniker is justified. In this train fit for a maharajah, you'll tour the former kingdoms that now constitute the north-central Indian province of Rajasthan, visiting eight cities in seven days. From India's "pink city" of Jaipur, you'll set out for the sandstone walls of Jaisalmer, a desert town and fortress. Then head out to Ranthambhor National Park, 400 square kilometers of forest and waterfalls—and tigers. See www.thepalaceonwheels.com.
