Machu Picchu Hot Springs (also known as Agua Calientes after its location in Peru) is a day-resort. It is just a short distance from the town's center and welcomes visitors all year.
The best thing about this resort for hot springs is the natural setting, surrounded by lush jungle forests and tall mountains. The majority of people travel by train from Cuzco to AguasCalientes. Some trek it with guided tours such as the Salkantay Trail or Inca Trail.
The hot springs open at 5:00 am in the morning. The best time to visit the hot springs is earlier in the morning for the most tranquil and pure experience. It remains open until 8:00pm every day.
There are 7 pools available, each with a different temperature. While most pools are cool to lukewarm, some claim they are hotter. A high wall separates the resort and the rushing river below. The hottest water is in the pool located closer to the vent.
Stone pools are lined with ceramic tiles and have a sandy flooring. The water is yellowish-greenish and murky. Some people recommend that you avoid this hotspring for health and sanitation reasons. Others say it's an item that must be included on any bucket list when visiting Machu Picchu. You will have to make your own decision. It is a good idea to take a shower after leaving the hot springs.
The hippie vibe in this area is relaxed during the day but turns into a more lively party at night. There's a bar that serves beer, cocktails, and snacks. Everybody gets a locker with an attendant upon entry.
What to bring
There aren't any accommodation at these hot springs but there are plenty of options in Machu Picchu Pueblo.
AguasCalientes – The resort is located about a kilometer northeast of town. It is a short, easy climb to get there. Continue on the pedestrian street to the Machu Picchu tickets office. Through the shops and restaurants of the town, you'll come to the end when you'll see towel rental facilities. Here you will find the ticket office, where you can pay an entry fee.
The walk from the town center takes around 15 minutes. For help locating the banos termsales, ask for directions if you are lost. You can also simply follow the Rio Aguas Calientes north to the hot springs.
