Levada do Caldeirão do Inferno

Surveyed in regional municipal records as a traditional gravity-fed water channel, Levada do Caldeirão do Inferno charts an unpatrolled course in Santana running between Caldeirão do Inferno, Ribeira Grande (1050 m) and Levada do Pico Ruivo intake (1030 m). The route showcases remarkable rural stonework, navigating dense forest cover, open cliffside promontories, and traditional hillside farmsteads. Because this corridor is not classified within the official IFCN network, walkers must recognize that it lacks regular ranger patrols, certified handrails, and formal storm condition updates.

• Gradients and elevation profile: The gradient profile follows the gentle hydraulic slope of the watercourse, punctuated by steep stone flights where access spurs join the channel.

Built to secure reliable irrigation for terraced hillsides, Levada do Caldeirão do Inferno was hewn directly into the basalt cliffs of Santana to sustain smallholder farming communities. Construction involved cutting through basalt buttresses and securing narrow masonry ledges above dizzying chasms, using volcanic stone found on-site to build long-lasting water retaining walls. The ongoing gravity flow along the masonry bench continues to irrigate traditional poios, testifying to the durability of 19th-century hydraulic craftsmanship in the face of harsh Atlantic weather.
