A bucket-list heritage journey, the Nilgiri Mountain Railway links the plains to the high, misty hills of Ooty via tea gardens, tunnels, and dramatic viaducts. Operating with vintage steam (and some diesel) locomotives, it’s part of UNESCO’s Mountain Railways of India and a favorite with families, students, and rail enthusiasts.

Board between Mettupalayam–Coonoor–Ooty for a slow, scenic climb through forests and tea estates; the lower ghat stretch offers the most dramatic gradients and views. Seats sell out early book on IRCTC, travel light, and aim for morning departures in the dry season. Pair the ride with Ooty/Coonoor sightseeing (Botanical Gardens, Doddabetta, Sims Park) for a classic Nilgiris day.
