Dawn breaks over As Conchas and the reservoir lies almost speechless—glass-dark water punctured by the stone ribs of half-submerged bridges and the square outline of Aquis Querquennis peeking where season and level allow. The five-seat electric boat slips forward in near silence; the motor hums, and the guide’s voice threads history into the bankside scrub as vultures wheel above the granite ridges.

Dawn breaks over As Conchas and the reservoir lies almost speechless—glass-dark water punctured by the stone ribs of half-submerged bridges and the square outline of Aquis Querquennis peeking where season and level allow. The five-seat electric boat slips forward in near silence; the motor hums, and the guide’s voice threads history into the bankside scrub as vultures wheel above the granite ridges.
This corner of the Baixa Limia - Serra do Xurés Natural Park sits on a porous frontier of Galicia and Portugal, carved by ancient rivers and human choices. Geology here is rugged—metamorphic schists and granite outcrops that channel crisp streams into the slow, dark basin created by the As Conchas dam. Centuries of human occupation—from Castro settlements to Roman outposts like Aquis Querquennis—lie partially underwater; when levels drop they reappear as weathered stones and buried roads.
Culturally the area is sparse and resilient: villages moved or abandoned when the reservoir rose, leaving stories, thermal springs, and trail routes to explore on land. Expect birdlife at the treeline and occasional mountain goats on rocky terraces; the guide will point out how upstream pollution and cross-border water management affect this fragile chain of life.
Practical note: trips run about 75 minutes from the Muíños pier, with small-group boarding and an expert skipper. Dress in windproof layers, bring binoculars and a waterproof camera, and plan for variable weather—spring and autumn bring the clearest archaeological sightings while summer offers longer daylight for photography.
The experience lasts about 75 minutes from boarding at the Muíños pier and returns to the same point.
