With 14 deluxe coaches (each named after a former Rajput state), two elegant restaurants and an onboard bar, the Palace on Wheels is a luxury seven-day train ride through India's royal past. Leaving from Delhi, it first visits the striking Pink City of Jaipur, home to Hawa Mahal (Palace of Winds) and nearby Amber Fort. Travel west to the desert town of Jaisalmer before chugging south to the charming Blue City of Jodhpur followed by tiger-spotting in Ranthambhor National Park. After Chittaurgarh Fort, it's the stunning White City of Udaipur on Lake Pichola followed by Bharatpur and Keoladeo Ghana National Park. Before looping back to Delhi, there's time for Agra's iconic Taj Mahal. This is seriously indulgent travel.
