Aguas Calientes is on the map because of its close proximity to Machu Picchu. It sits at the bottom of the valley and serves as the main access point to the famed sight. The city itself is not very attractive, but in all likelihood, you will spend at least one night here during your visit to Machu Picchu.

People head to Aguas Calientes and Machu Picchu by one of two ways. Either you walk, or you take the train. Peru Rail offers several rides daily from Ollantaytambo, which is almost two hours from Cuzco. The best way to Ollantaytambo is by collectivo, which can be picked up on Calle Pavitos for 15 soles a person. It's worth spending a night in Ollantaytambo and visiting its sights before traveling on to Machu Picchu. The trip to Aguas Calientes is just under two hours and you should purchase your tickets in advance. Prices begin at US$35 and jump up dramatically from there. If Peru Rail is full, there are alternative services offered by Inca rail and Machu Picchu Rail for comparable prices.

I more adventurous alternative is to hike to Aguas Calientes. It's about a seven hour hike and you must pick up the Inca Trail. Ask around town and consult your guide book to fully understand the route you must take as there are a handful of different options.

You can catch a bus up to Machu Picchu from Aguas Calientes for about US$17.00. This includes the return trip. It's a steep hike to walk up to the ruins so be prepared if that is your plan. You must purchase a ticket to the ruins at the Cultural Centre in Aguas Calientes. The ticket is good for one entry during a three day period. Be sure and bring some snacks and water with you because once you're inside the grounds the prices are extremely expensive and overpriced.
