Train

Trains run along four different routes: between Cusco and Machu Picchu, between Cusco and Lake Titicaca, and between Lake Titicaca and Arequipa. The second highest train in the world runs between Lima and Huancayo, one or two times a month between May and November; tours last four days. Tickets can be purchased at train stations, through travel agencies, or online. During holidays or high season, it's best to get your tickets in advance.

Two companies offer train service to Machu Picchu. PeruRail, which has served the route since 1999, is operated by Belmond—the same company that runs one of the most luxurious and famous trains in the world, the Venice Simplon Orient Express between London and Venice. It travels to Machu Picchu from Cusco (technically from the nearby town of Poroy, about 20 minutes outside the city) and the Sacred Valley towns of Ollantaytambo and Urubamba. Inca Rail, which began service in 2010 and merged with Andean Railways in 2012, travels between Ollantaytambo and Machu Picchu. Foreigners are prohibited from riding the very inexpensive local trains that cover the route. The Machu Picchu station is not at the archaeological site itself, but in the nearby town of Aguas Calientes.

In May 2017, PeruRail completely revamped its Andean Explorer train service to points south of Cusco. It is now a sleeper train including a luxury dining car and a spa, and the company offers several different options, including single-day trips between Cusco and Lake Titicaca and three-day/two-night tours that take in Arequipa as well. Each departs on a different day of the week, depending on the trip chosen. The newly revamped Andean Explorer from Cusco to the lake is US$1,800 for two passengers, leaving at 11 in the morning from Cusco; culminating in a sunrise breakfast at Lake Titicaca; and including lunch, tour of Raqchi, tea time, predinner drinks, dinner, and, of course, your bed. Note that there are two different train stations in Cusco. Estación Poroy serves the Machu Picchu route, and Estación Wanchaq serves the Lake Titicaca route. Reserve and purchase your ticket as far ahead as possible, especially during holidays or high season. Reservations can be made directly with PeruRail through its website or through a travel agency or tour operator.
