Around the Lagoa do Fogo area you visit the crater and hike to its lake which is part of the Nature Reserve of Lagoa do Fogo. On the slopes of this volcano you see natural volcanic and geothermal production structures, we take you to the Natural Monument of Caldeira Velha with its hot springs, the Salto do Cabrito waterfall, the Caldeiras fumaroles, Lombadas valley, Lagoa do Congro Maar crater, Vila Franca do Campo hill Chapel, Caloura´s Port and Ribeira Grande historical center.
Lagoa do Fogo is one of the largest of the waterbodies in the Azores, and occupies the central caldera of the Água de Pau Massif, in the central area of the island of São Miguel.
The caldera is the youngest volcano on the island of São Miguel, formed approximately 15 000 years ago, resulting from the collapse at the top of the volcano, some 5000 years ago.
The last eruption occurred in 1563. It falls within the borders of the civil parishes of Conceição, Matriz and Água de Alto, in the municipalities of Ribeira Grande and Vila Franca do Campo, respectively.
- Length: 3 km (2 mi)
- Width: 2.5 km (2 mi)
- Depth: 30 m (98 ft)
- Basin: 21.82 km2 (8 sq mi)
Besides its natural wealth – and very exotic – and diversity of vegetation and fauna, the Caldeira Velha is also much visited by those who want to bathe in the warm and thermal waters, with medicinal characteristics.
The water comes from hot springs of thermal origin, forming cascades, and channels with brown tone due to the abundance of iron.
One of the most sought after places is the pool where you can be as if you were in a jacuzzi.
The Caldeira Velha is located in the crater in the Volcano of Fogo and has fumaroles, zones of degassing, and a spring of thermal water. There are two pools of hot water: one can reach 25 degrees celsius and another, with water from the fumaroles, which varies between 35 and 38 degrees celsius.
- It is crossed by a stream with small dams fed by hot springs of thermal origin
- It is worth noting the abundance of boilers, fumaroles and rocky outcrops of varied colors
- Its highest point is at 628 meters and is part of the foothills of the Volcano of Fogo
This lagoon occupies a maar explosion crater, the result of a water table, located in one of the most active geological faults of the island of São Miguel.
The peculiarity of this explosive crater formed some 3,900 years ago is that it originated in phreaomagnetic explosions in which the rising magma has reached contact with existing groundwater levels in the underlying formations.
Due to its genesis the Lagoa do Congro presents characteristics that distinguish it from most of the lagoons of the island of S. Miguel.
Its main feature is that it is embedded in the surrounding region, relatively flat, in the form of a large open hole in the surrounding area, as opposed to occupying the top of a well-defined volcanic cone.
- The lagoon is located a few kilometers from Vila Franca do Campo
- It is located about 5.5 kilometers from Lagoa do Fogo.
- It has a perimeter of 1.25 kilometers.
Our goal is to meet your best expectations on your visit to our island!
