This lagoon complex is a large pool of water that constantly receives water from the springs through waterfalls and also from underground water. Its banks are alive with reeds and low scrub, so entry is possible from any point. The bottom is generally sand in the form of heavy mud.

About 25 minutes from Viseu, we find the dam with a maximum depth of 20 meters and an interesting underwater route with a maximum depth of 9 meters. On-site we can find a bus, a horizontal tunnel passage, a small sailboat, a construction silo, 2 light cars, and 1 jet plane

Remains of old sunken pontoon constructions next to an outfall that is lost in the sea. The outfall supports give an eerie look on dives rising from the sea floor to support a huge endless pipe. Fantastic place for night dives with lots of life

This dive takes you into a shelter in the mouth of the port of Pasajes, formed by multiple slabs. They are extensions of the mountain that fade in the entrance channel of the port. A variety of archaeological remains are seen here.
