What Is the Boiling River?
Deep in the heart of the Peruvian Amazon lies one of the world’s most extraordinary natural wonders — the Boiling River (Shanay-Timpishka). This rare geothermal phenomenon is a river that literally boils, with temperatures reaching up to 90°C (194°F). The water is so hot that small animals or leaves that fall into it are instantly cooked.
Where Is It Located?
The Boiling River is located in the Mayantuyacu region, about 700 kilometers away from the nearest active volcano making it a geological mystery. Most hot rivers on Earth are found near volcanic activity, but this one isn’t, which puzzles scientists to this day.
The Science Behind It
According to research led by geoscientist Andrés Ruzo, the Boiling River is heated by deep geothermal systems. Rainwater seeps deep into the Earth’s crust, gets superheated by geothermal energy, and then reemerges through cracks along the riverbed, creating a steaming, natural cauldron.

Cultural and Spiritual Significance
For local Asháninka tribes, the river is sacred. They call it Shanay-Timpishka, which means “boiled with the heat of the Sun.” Shamans use its steam and mineral waters for traditional healing ceremonies, blending science and spirituality in a truly unique way.
Visiting the Boiling River
Although remote, adventurous travelers can visit the Boiling River through guided eco-tours. However, visitors must exercise extreme caution temperatures vary from warm to dangerously hot, and the terrain can be slippery.
