The Lapa dos Dinheiros river beach is in perfect harmony with nature. Located in the parish of Lapa dos Dinheiros, on the Caniça River, a right-bank tributary of the Alva River, this bathing area is nestled in a mountainous landscape dominated by the Lapa Souto (south of Lapa) and imposing granite outcrops. With clear water, very appealing for swimming, the beach boasts the award for accessible beach and has lifeguards and a bar available to visitors. The rugged terrain of the valley causes the river to form a succession of small waterfalls nearby. The Lapa Souto, in addition to its valuable collection of centuries-old chestnut trees, is also home to a high level of biodiversity. From the bridge, a pedestrian path leads to the Moura Hole and a viewpoint over the Caniça Waterfalls. The Buraco da Moura is a natural cave system created by the sliding and accumulation of large granite blocks, which formed a complex system of rooms and galleries. How to get there? Once in Seia, follow the EN231 to S. Romão. From there, continue uphill for about 5 km, toward Loriga/Lapa, until you find the sign for Lapa dos Dinheiros on the left. Once inside the town, simply follow the beach signs. Coordinates: 40º 23′ 07.0″ N / 7º 41′ 50.1″ W

Located at an altitude of approximately 1,600 meters, Lagoa Comprida is the largest water reservoir in the Serra da Estrela, intended for hydroelectric generation. This natural lake lies in a wide depression of glacial origin, approximately one kilometer long, which fed the Covão Grande glacier. Numerous glacial scars are visible along its banks, making this lake one of the most interesting geomorphological sites in the Serra da Estrela. Construction on this lake began in 1911, and by 1914, it was already six meters high. Later, in 1965, it underwent heightening work that increased its height to 28 meters, currently boasting a storage capacity of approximately 14 cubic hectometers, flooding an area of approximately 80 hectares. Small streams of water flow into this lagoon, as well as water retained in the Covões dos Conchos and Covões do Meio and carried to this lagoon through underground tunnels.

Here you ride on a wide dirt path that winds its way through the thick vegetation of the forest. The scents are wonderful and the shade gives you a bit of relief even on the hottest days.

Lagoa Comprida is the largest glacial lake in Serra da Estrela, Portugal, and one of the most iconic spots in the Natural Park. Its name, meaning "Long Lake," perfectly describes its elongated shape, nestled between the surrounding peaks. Originally a glacial lake, it was artificially enlarged with the construction of a dam in the early 20th century for hydroelectric power generation, becoming an important reservoir. Its crystalline waters reflect the sky and the rugged surrounding mountains, creating breathtaking views. It is a popular starting point for hikes and treks to other lagoons and peaks, and offers a sense of grandeur and serenity typical of alpine environments.
