7 Lakes and Reservoirs to Discover in Portugal

While Portugal is often celebrated for its golden Atlantic coastline, the interior of the country holds some of the most serene and beautiful freshwater landscapes in Southern Europe. From high altitude glacial lagoons to vast, mirror-like reservoirs, these bodies of water offer a different perspective on the Portuguese landscape.

Whether you are looking for the rugged beauty of the mountains or the rolling plains of the south, these seven spots provide a perfect escape from the bustle of the coastal cities.

## The High Altitudes of the North

### 1. Lagoa Comprida (Serra da Estrela) Set high in the Serra da Estrela, Lagoa Comprida is the largest and most famous of the lagoons in the Serra da Estrela. This is a natural glacial lagoon that was later expanded by a dam. The landscape here is dramatic and rocky, often covered in snow during the winter months. In the summer, the deep blue water contrasts beautifully with the grey granite boulders. It is a place of absolute quiet, reachable by winding mountain roads that offer panoramic views of the entire region.

### 2. Lagoa da Ervedeira (Leiria) Located near the coast but tucked away in the pine forests of the Leiria region, Lagoa da Ervedeira is a rare example of a natural freshwater lake in this part of the country. It is a popular spot for locals who want to enjoy a peaceful day surrounded by nature. The lake features wooden walkways that allow for gentle strolls around the water's edge, making it an ideal stop for those traveling between Lisbon and Porto who want to see a different side of the central region.

## The Great Reservoirs of the South and Interior

### 3. Alqueva Reservoir (Alentejo) The Alqueva is a true marvel of engineering and one of the largest artificial lakes in Europe. Created by the damming of the Guadiana River, it transformed the landscape of the Alentejo region. The water stretches as far as the eye can see, dotted with small islands and surrounded by olive groves and cork oaks. The area is also a certified Dark Sky Reserve, meaning the lack of light pollution makes it one of the best places in the world for stargazing after the sun sets over the water.

### 4. Castelo de Bode Reservoir (Central Portugal) Situated on the Zêzere River, Castelo de Bode is one of the most important reservoirs in the country. It is a favorite destination for those who enjoy water activities and peaceful retreats. The shoreline is incredibly jagged, creating dozens of hidden coves and inlets that feel entirely private. The surrounding hills are thick with eucalyptus and pine, giving the air a fresh, clean scent. It is a wonderful area to explore if you are visiting the historic city of Tomar, which is located just a short drive away.

### 5. Santa Clara Reservoir (Alentejo) Located in the southern part of the Alentejo, near the border with the Algarve, Santa Clara is one of the most remote and pristine reservoirs in Portugal. Because it is further away from the main tourist hubs, it remains incredibly quiet. The water is known for being exceptionally clean and calm. The surrounding hills are gently rolling and sparsely populated, offering a sense of solitude that is hard to find elsewhere.

## Hidden Gems in the North and Center

### 6. Albufeira do Azibo (Trás-os-Montes) Way up in the northeast corner of Portugal, in the region of Trás-os-Montes, lies the Azibo Reservoir. This area is a protected landscape and is highly regarded for its biodiversity. The water is clear and surrounded by lush greenery and hills. It is a perfect example of how human intervention can create a balanced ecosystem that supports local wildlife. The nearby villages still retain their traditional stone architecture, offering a glimpse into the rural life of Northern Portugal.

### 7. Aguieira Reservoir (Coimbra Region) Nestled between the cities of Coimbra and Viseu, the Aguieira Reservoir is formed by the Mondego River. It is a large, sprawling body of water with many arms that reach into the forested valleys. The area is home to several high-end riverfront stays and is a popular spot for those who want to combine a visit to the historic University of Coimbra with some time in nature. The reflection of the pine trees on the still water at dawn is a sight to behold.

## Practical Information for Travelers

Visiting these lakes and reservoirs requires a bit of planning, as many are located in rural or mountainous areas where public transportation is limited. The best way to reach these sites is by road, allowing you to stop at small villages and viewpoints along the way.

While some of these locations offer seasonal amenities like small cafes or equipment rentals, others are completely wild. It is always a good idea to bring water and snacks, especially when heading into the Serra da Estrela or the deep Alentejo. Always check local weather conditions, particularly in the mountains, as fog and snow can arrive quickly in the winter.
