Another attractive natural feature of the country is its many bodies of water. Lakes in Portugal provide beautiful spots to get away from the city and soak up the surrounding nature.
You can find a selection of beautiful lakes on the Portuguese mainland as well as its islands. For the most part, not many tourists are aware of these overlooked gems where you can find a moment of peace and tranquility. That’s why we’ve put together this list of the best lagoons and lakes in Portugal that you should visit.
Lagoa da Vela
Located near Figueira da Foz is one of Portugal’s most popular lakes, Lagoa da Vela. Frequented by those seeking adventure, the lake is the perfect place to go kayaking and canoeing.
In the area surrounding Lagoa da Vela you’ll find several hiking trails, perfect for anyone looking to immerse themselves in nature. Nearby Figueira da Foz is a seaside resort in the Coimbra district. You could spend a night there enjoying the fresh local fish, walking along the waterfront promenade, trying your luck at the casino, and, of course, visiting the beach.
The island of São Miguel is part of the archipelago of the Azores. This beautiful island is home to the spectacular Lagoa do Fogo, the Lagoon of Fire. As a protected area, no construction is allowed in the areas surrounding the lake in an effort to preserve its natural beauty.
The lake’s interesting name comes from how it was formed. The crater lake formed after the eruption of a volcano many years ago. This volcanic activity caused a collapse and formed a crater, which is where the emerald lake now sits. The volcano’s magma chamber is located a few kilometers below this dazzling body of water. Today, the Lagoon of Fire is a popular spot for hikers and bird watchers to visit.
Also in the Azores is Lagoa das Sete Cidades, the Lagoon of the Seven Cities, another lake found in the crater of a dormant volcano on São Miguel island. This twin lake is one of the most beautiful lakes in the country as it is made up of two colors. One side of the lake is blue, while the other is green. These eye-catching lakes are best enjoyed from the Vista do Rei viewpoint that you can hike to.
A mere ten kilometers from the lake lies Ponta Delgada, where you can enjoy some Gothic-style architecture and lively cafés.
Pateira de Fermentelos is the largest natural lake in Portugal and the Iberian Peninsula. You’ll find it on Portugal’s mainland, in a triangle between the Águeda, Aveiro, and Oliveira do Bairro municipalities.
