The Caldeiras das Furnas – also known as Fumarolas das Furnas, are one of the main points of tourist interest of the island of São Miguel. This enigmatic place is worth visiting and you cannot miss a visit to the site on your way through the Azores Archipelago. As in any place where magma is closer to the surface, the Smoky Field of Vila das Furnas and the Smoky Field of Furnas Lagoon are areas where the imposing volcanic manifestations occur. These calderas are small rainwater ponds formed in the craters of the dormant volcano since 1630. These emerged when the top of the volcano cone collapsed in its last eruption.

Combined with the magma that is close to the surface, the rainwater that has accumulated in these holes, reaches very high temperatures thus causing the fumaroles, springs and hot springs. However, the fumaroles, in addition to sharing the same boiling state as water, emit vapors and gases with a strong sulfur odor.

The main Smoky Field is located in the center of Vila das Furnas – here you can observe the fumaroles and the boilers with temperatures ranging between 70 º and 100 º

This one is the secondary Fumarlic Field – Fumarolas da Lagoa das Furnas, in my opinion are more interesting to visit.

In addition to the Main Smoky Field located in Vila das Furnas, there is a second called “Fumarolas da Lagoa das Furnas” – as its name implies, this field is situated next to the Furnas Lagoon.

Here you can witness the Removal of Pots With Portuguese Stew

Savoring cozido das Furnas is something you can’t miss when you pass through Furnas Lagoon. However, in order to have a greater sensory experience of this moment you must watch the removal of the pots from inside the fumamolas.

As lunchtime approaches, around noon, local restaurant managers dig up the pots that remained inside the holes built in the fammo for the past six to seven hours.

Thus, if you want to visit the Fumarolas da Lagoa das Furnas this is the most interesting time of the day to do so.
