They are located in the historic center of Ourense, on Rúa das Burgas / Praza das Burgas, next to the Barbaña River. They are perfectly integrated into the urban environment, near the Cathedral and the Roman Bridge. Explored since Roman times, these waters were the origin of the city (Aquis Auriensis), and the remains include a 1st-century AD pool-sanctuary and votive stones dedicated to an indigenous deity. The water flows at approximately 64–68°C, with a flow rate of about 300 liters per minute. Rich in minerals such as metasilicates, fluoride, lithium, bicarbonate, and sodium, they are recommended for pruritic skin conditions and rheumatism. Recent studies support their beneficial effect on acne after washing with thermal water.

The Monastery of San Pedro de Rocas is one of the oldest and most unique monasteries in Galicia, located in the municipality of Esgos, in the province of Ourense. This monastery stands out for being partially excavated in the rock, which gives it a unique and mysterious character. The foundation of the monastery dates back to the 6th century, although most of the structures visible today date from the 9th and 10th centuries. The monastery church is composed of three naves excavated in the rock, with a series of anthropomorphic tombs also carved in the stone. Outside, you can see a bell tower that was added in the 15th century. San Pedro de Rocas is known not only for its architecture, but also for its natural environment, surrounded by forests and mountains, making it a place of great beauty and tranquility. The monastery has been declared a Historic-Artistic Monument and is an important tourist and pilgrimage destination.

Mirador da Pedra Longa, a majestic rock formation in the shape of a vertical monolith whose height exceeds 7 meters and is made up of just one piece of stone. Rain and wind have been responsible for sculpting this wonderful work of art for millions of years. It is accompanied by the special background that the valley and the Sil canyon give it. From here you will see a good stretch of the Sil River, from Pombeiro (Pantón) to the mouth of the Cabe River, in A Barca. Also in the distance you will appreciate the high and vertical slopes of the canyon in Sober, in the parishes of Belmonte or Santiorxo.
