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
This beautiful crater lake is surrounded by the steep peaks of the ancient Furnas mountain and its lush, green rim. Visitors can enjoy several hiking trails around the lake, as well as several beautiful parks and the iconic Neo-Gothic Chapel of Nossa Senhora das Vitórias. Rent a kayak or paddle board and venture out to the middle of the lake to enjoy 360° views of the breathtaking scenery. While you're there, be sure to stop by the bubbling caldeiras to see the geothermal activity and catch the local restaurants coming to cook or pick up their Cozido stew from the fumaroles in the ground.
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.

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!
4. Bolos Lêvedos
Bolos lêvedos are a yummy flatbread from Furnas that is a sweeter, larger version of an English muffin, and there is nothing better than taking a soft, fluffy bite of one fresh out of the oven.

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.
