Caldeira das Furnas

About

The Caldeira das Furnas, located in the east of the island of São Miguel in the Azores, is a dramatic volcanic landscape where steaming hot springs and geysers spill from the earth’s crust into a picturesque crater lake. Visitors wander around the bubbling waters of Lagoa das Furnas, bathe in the mineral‑rich thermal pools of the Terra Nostra Park, and witness the fire‑red fumaroles that give the valley its famously sulphurous smell. A highlight of the experience is the traditional stew “Cozido das Furnas”, literally “Furnas stewed”, which is slow‑cooked in the geothermal heat that emanates from the earth. Whether you’re a geologist curious about volcanic activity or simply seeking a unique, nature‑infused adventure, the Caldeira offers a rare opportunity to see a living volcano and enjoy some of the freshest hot‑spring‑heated cuisine in Portugal. Beyond its geothermal wonders, the valley is dotted with botanical gardens, historic churches, and cultural sites such as the Thermal Spa of Furnas. The area’s mild, oceanic climate means that visitors can comfortably explore the bubbling streams and lush greenery year‑round, with especially pleasant evenings in late spring and early fall. The combination of earth‑shaping forces, culinary tradition, and breathtaking scenery makes the Caldeira das Furnas a must‑visit destination for any traveler craving natural wonder and culinary adventure. Plan your trip with a day dedicated to the valley’s main attractions: start at the Terra Nostra gardens in the morning, then head to the thermal pools and the steaming aquifer fields, and perhaps finish with a steaming pot of Cozido in the evening. The valley is open daily, and most attractions are free to enter, though a small fee may apply at certain visitor centers or guided tours. The site’s status as a living volcanic zone offers both adventure and safety warnings, ensuring a memorable, educational, and relaxing visit.
