The name 'Poço do Inferno' translates to 'Well of Hell,' a common naming convention for deep or difficult-to-reach natural pools in Portuguese folklore.
The site sits within the Zêzere Glacial Valley area, a prominent landscape feature of the Serra da Estrela mountain range.
The waterfall is prone to freezing during extreme winter cold spells, creating unique ice formations.
Poço do Inferno is a high-altitude waterfall located in the Serra da Estrela Natural Park, situated at approximately 1,100 meters elevation. The waterfall is formed by the Leandres stream, which drops over a steep cliff face into a pool carved into the granite terrain. It is recognized as one of the highest altitude waterfalls in mainland Portugal. The surrounding landscape is characterized by glacial valley formations typical of the region. The waterfall's volume is heavily dependent on seasonal rainfall and snowmelt patterns. The site is accessible via a short walking trail connected to the local road network in Manteigas.
The wooden footbridge located at the base of the trail provides a clear, unobstructed view of the waterfall drop.
Wear sturdy, closed-toe hiking footwear, as the paths near the pool are often wet and slippery.
Monitor local mountain weather forecasts, as fog and temperature drops occur rapidly even in summer.
Do not attempt to swim in the pool; the water is extremely cold, and the depth is unpredictable with hidden submerged obstacles.
Access may be restricted during heavy winter snowfall when mountain roads are closed by local authorities.
Stay on marked trails to prevent soil erosion; do not remove rocks or vegetation from the protected natural park area.
