What is Caldeira das Sete Cidades?

Caldeira das Sete Cidades is the collapsed summit of a large volcano that fell apart after a big explosive eruption around 36,000 years ago. In fact, the eruption was so significant that the magma chamber emptied and could not support the elevation anymore. This volcanic structure has an almost circular shape, measuring about 5.3 kilometers in diameter and reaching depths of up to 630 meters. Its imposing size makes it one of the largest volcanic calderas in the Azores.
Did you know
Inside the caldera are several volcanic features, including domes and cones. Among them are smaller craters that are now filled with water, just like Lagoa de Santiago, Lagoa Rasa, and 15 more lagoons.
The most famous one, Lagoa das Sete Cidades, is composed of two connected lakes: Lagoa Azul and Lagoa Verde (blue and green lakes). These lakes are at approximately 260 meters above sea level and are the largest freshwater system in the Azores. Finally, inside the caldera, people decided to settle and founded a village of about 700 inhabitants by the blue lake.

Plan Your Visit to Caldeira das Sete Cidades

How to Get to Caldeira das Sete Cidades
Reaching Caldeira das Sete Cidades from Ponta Delgada – São Miguel’s biggest city – is quite simple. By car, the journey takes about 30 minutes, following well-maintained roads on the south coast, passing by the airport and Relva village. When you find the indication towards Sete Cidades on your right side, you will gradually climb toward the western part of the island. Renting a car is the most flexible option, especially for reaching viewpoints and starting points of hiking trails. You could also grab a taxi, but if you want to explore inside the caldera once the taxi is gone, you will need to walk long distances.
Public transportation is also available, with buses connecting Ponta Delgada to the village of Sete Cidades. However, schedules can be limited and unreliable. Plus, it takes more time as the driver will pass by every bus stop on the way. Guided tours are another convenient alternative, particularly for travelers who prefer to have explanations on the island and the volcanic complex.

Best Time to Visit

Caldeira das Sete Cidades is a good place to visit year-round, but weather conditions play an important role in the experience. Spring and summer are generally the best seasons, offering higher chances of clear skies, mild temperatures, and good visibility from the viewpoints. However, we do have the 4 seasons in a day, so it is best to check the weather cameras to make sure you don’t go there for nothing. Autumn also provides pleasant conditions, with fewer visitors and softer light, which is ideal for photography.
Early mornings or sunset times are the best to observe the breathtaking view from the miradors, as they will be less crowded. Especially if you are visiting during the high season, prefer those times to visit. By 10 am, the touristy spots are already crowded in July and August.
