Explore Furnas: A Fascinating Geothermal Haven

Furnas is a small civil parish with less than 1,500 inhabitants located on the southeast side of São Miguel Island, about 50km (31 mi) from Ponta Delgada. You can spend a full day here without ever getting bored because there’s a lot to visit and learn about. What makes Furnas Valley unique is that the area is a dormant volcanic crater. Although the Furnas volcano last erupted in 1630, you can feel, see, and smell the geothermal activity all around you in the form of steaming fumaroles, thermal pools, and natural mineral springs around every corner. And, let’s not forget the tasty treats that get cooked up in all this geothermal heat. The locals utilize the heat of the ground to cook the famous Cozido stew, and also use the mineral waters in several recipes for cheese, pastries, bread, meats, and more.

So, what is there to see and do in Furnas? We'll give you the inside scoop. 

 

1. Furnas Lake in São Miguel Island, Azores

2. Cozido das Furnas: A Delectable Traditional Dish from São Miguel Island

A longstanding tradition among the locals, this beloved popular dish is a Portuguese stew (cozido) cooked in holes known as fumaroles that are dug in the hot volcanic soil in Furnas. The stew is comprised of a carefully layered pot of pork, beef, chicken, sausages, potatoes, carrots, cabbage, and kale that is cooked slowly in the ground for around 6 hours. Every restaurant in the town of Furnas serves its variation of this dish, so there is no shortage of places for you to try it!

3. Caldeiras of Furnas, São Miguel Island, Azores

In the center of town, Furnas boasts close to 30 bubbling, steaming calderas and fumaroles of different temperatures and biological compositions, the strong smell of sulfur wafting through the air at every turn. Unsurprisingly, the locals have made the best of having these natural steam pots around. Temperatures range from 70ºC (158ºF)  to 100ºC (212ºF) which is perfect for cooking (but dangerous to get too close to!)  You can stop in for a snack of freshly boiled corn on the cob, cooked in one of the caldeiras in town!

7. Vale Cheese in Furnas, São Miguel Island, Azores

This cheese factory is a small, family-run business that started with just a small dairy farm.

Another beautiful garden but almost secret garden in Furnas is the ‘’Jardim Dona Beatriz do Canto’’ also known as ‘’Jardim das Murtas’’.

This romantic 1860 garden, located on Rua de Santana, has an area of 3.7 ha and from its botanical heritage stands out in the presence of remarkable dimensions threes such as Sequoias.
