Aguas Calientes gets its name from the hot springs on the hill above town — a stack of open-air mineral pools about a 10-minute uphill walk from the main square. After a day climbing the citadel’s switchbacks they are a small, cheap luxury that most day-trippers skip because they’re on the next train out.
Peruways’ guided visit covers the geology (thermal activity from the nearby fault line, iron and sulphur content giving the water its colour) and the practical side: towel rental, lockers, water temperatures ranging from 38°C to 44°C across the four main pools. Open 5am to 8pm, so an evening soak after a 6am entry at Machu Picchu is very doable.
The pools sit under a lip of forest, so the soundtrack is the Vilcanota river and the local birds, not street traffic. Locals believe the mineralised water helps with altitude recovery; the science is weaker, but a hot soak at 2,040m after six hours of walking is its own argument.
Contact Peruways to add the hot springs to a Machu Picchu overnight. They pair naturally with a second morning on the citadel.
