Natural Wonders: Waterfalls & Caves

This collection highlights geological landmarks across the Azores and the Algarve. It includes the Gruta de Benagil sea cave with its natural skylight and the Gruta das Torres, Portugal's longest lava tube. On São Miguel, thermal activity defines sites like Ponta da Ferraria’s oceanic hot springs and the iron-rich pools of Caldeira Velha. The list also features secluded waterfalls like Salto do Cagarrão and the thermally-fed Cascata da Ribeira Quente, illustrating the diverse volcanic and coastal formations of the Portuguese landscape.

Caldeira Velha

Thermal waterfall located on the slopes of the Fogo Volcano. The water is naturally heated by geothermal activity and flows into a pool surrounded by tree ferns and Macaronesian forest.

Gruta de Benagil

A coastal sea cave in the Algarve accessible only by water. It features a large natural dome with a circular opening at the top and a secluded sandy beach inside.

Caldeira Velha

Geothermal pools with iron-rich waters maintained at temperatures between 25°C and 39°C. The site includes an Environmental Interpretation Center focused on the volcanic origin of São Miguel.

Ponta da Ferraria

A unique coastal formation where geothermal springs heat the ocean water within a natural rock pool. The warm water is best experienced during low tide.

Gruta do Carvão
