Quick Summary: The Baños Termales in Aguas Calientes are real geothermal pools in a cloud-forest gorge setting, they cost around 20–25 soles to enter, and they genuinely deliver — if you go at 6 AM or after 6:30 PM. Go between 11 AM and 4 PM on a peak day and you’ll be sharing a small pool with thirty strangers. Timing is everything here, and most travellers get it wrong because no one tells them upfront.
Rather skip the logistics? Your Machu Picchu entry ticket, train, bus and a licensed guide are booked for you. If a circuit sells out or a train is late, we sort it out, not you.

The name “Aguas Calientes” literally means “hot waters,” and the town exists because of these springs. The Baños Termales are a set of five to six public thermal pools cut into a steep hillside above Avenida Pachacutec, fed by genuine geothermal springs that emerge naturally from the Andes. The water is hot — ranging from about 35°C in the cooler entry pools to 42°C in the hottest — and slightly sulphurous. You’ll smell the sulphur as you approach. That’s how you know it’s real.
The setting is legitimately good. Pools are carved into a hillside surrounded by cloud-forest vegetation, with the sound of an Urubamba tributary rushing nearby. When the mist rolls in at dusk or the steam rises off the water against the jungle backdrop, it earns its reputation. This isn’t a hotel spa with a rooftop plunge pool — it’s a municipal thermal facility run by the Municipalidad Distrital de Machu Picchu with basic changing rooms, coin-operated lockers, a small rental stand, and a snack area. Bring your own towel and swimsuit. Bring a small padlock if you want to actually secure your locker.
Entry costs approximately 20–25 soles (roughly $5–7 USD) for adults, set by the municipality and subject to change. Pay at the official booth at the gate — not from street vendors on Pachacutec who claim to offer “discounted entry.” There is no legitimate discount. Opening hours run approximately 5 AM to 9:30 PM daily, though these are managed by the municipality and shift seasonally.
Go at the wrong time and you’ll be in a crowded, warm public pool surrounded by large tour groups. Go at the right time and you’ll practically have the place to yourself in one of the more atmospheric spots in the Machu Picchu area. The difference between these two experiences is entirely about when you show up.
Go at these times:
Avoid these times:
“We went at 7 AM the morning after Machu Picchu and practically had the pools to ourselves. Steam rising off the water with jungle behind it — one of the most peaceful moments of the whole trip.” — KatarinaNZ, New Zealand, September 2025
Walk straight up Avenida Pachacutec from the Plaza de Armas. The entire street is pedestrian, uphill, and lined with restaurants and shops on both sides. At the top of Pachacutec the road narrows, and the entrance gate and ticketing booth appear on the left. You cannot miss it. No taxi needed, no shuttle bus — just your legs and about 10 minutes.
What to bring:
What to watch for at the entrance: Men on the uphill section of Pachacutec and near the gate offer “private pool access” or “premium entry.” Ignore them completely. The municipal hot springs have one entrance, one ticket price, and no private pools available from street vendors. Walk past without engaging.
Honestly — yes, if the timing works for your schedule and your legs can handle one more short uphill walk.
The most practical sequence for overnight visitors: Enter the ruins at 6 or 7 AM, finish by noon, take the shuttle back to Aguas Calientes, have a proper sit-down lunch on Pachacutec, rest at your hotel for an hour, then walk up to the springs at 6 PM. Back for dinner by 8:30 PM, asleep by 10 PM ahead of an early train. That sequence fits cleanly and uses the evening window perfectly.
For day-trippers catching an afternoon or evening train: the math is tight. Factor in a 20-minute round-trip walk, a minimum 45-minute soak to justify the trip, and changing time — you need a clear 90 minutes. If your train is before 4 PM, skip the springs and save them for a return visit. If your train is at 6 PM or later, the 3:30–5:30 PM window works.
Worth it if you:
Less worth it if you:
“After five hours at Machu Picchu my travel partner dragged me. I did not want to go. She was completely right — pools in the evening with steam and jungle all around, nobody else there. Worth it.” — DominicFR, France, August 2025
Are the hot springs natural or artificially heated?
They are genuinely natural. The water emerges from geothermal springs fed by volcanic activity deep in the Andes — the same geological system that created the mountain chain. The slightly sulphurous smell you notice on approach is the clearest confirmation that the heat is coming from the earth, not a boiler room. This is what distinguishes Aguas Calientes from hotel-operated “thermal” facilities that pump in and reheat water.
Are the pools clean enough to use?
The municipality drains and cleans the pools on a regular maintenance cycle. By most traveller accounts the water is adequately maintained, though as with any high-volume public thermal facility, standards vary day to day. They are not filtered or chemically treated the way a hotel pool would be. Travellers with open wounds or active skin conditions should use personal judgment; most people use the pools without issue.
Can children use the hot springs?
Yes. Families are a regular sight at the Baños Termales. The cooler pools at 35–37°C are more appropriate for children than the hottest pool at 42°C. There are no formal age restrictions but no lifeguard is on duty — parents need to supervise. The pool edges can be slippery.
What’s the exact entrance fee and where do I pay it?
In early 2026, the fee is approximately 20–25 soles per adult (~$5–7 USD). Children pay a reduced rate. Pay only at the official ticketing booth at the entrance gate at the top of Avenida Pachacutec. The fee is set by the municipality and collected by an attendant — not by anyone on the street outside. Carry soles in small denominations; the booth does not reliably provide change for S/100 notes.
Is the walk to the hot springs safe at night?
The walk up Avenida Pachacutec to the entrance is safe — it’s a well-lit pedestrian street used by tourists throughout the evening, and the springs are open until around 9:30 PM. The walk back down is equally fine. The issue is not the route; it’s the entrance-area touts who increase in presence after dark. Walk past them, pay at the official booth, and you’ll have no problems.
Entry prices and opening hours are set by the Municipalidad Distrital de Machu Picchu and change periodically — figures here reflect early 2026 conditions and should be confirmed at the gate on arrival. Pool maintenance schedules are managed by the municipality; there is no publicly available water-quality data, so hygiene assessments in this article are based on traveller reports rather than independent testing. Reviewers should flag if official water-quality documentation becomes available for inclusion.
