Accessible only by train, the picturesque tourist town of Aguas Calientes is the jumping off point for Machu Picchu.

Nestled beneath soaring cloudforest-smothered mountains, the town is famous for its thermal baths - a series of brown, lukewarm pools  filled to the brim with  blissed-out travellers.

Aguas Calientes is also known as Machu Picchu Pueblo and is a scenic four-hour train ride from Cusco. Unless you've walked here on one of the handful of 'alternative' Inca trails, the train is the only way of reaching the town.
