The lake's water comes from underground streams flowing through the limestone mountains of the Alta Garrotxa.
La Draga is one of the oldest lacustrine prehistoric settlements in Europe, dating back to approximately 5000 BC.
The water level remains relatively constant due to the complex internal drainage system through the karst soil.
During the 1992 Olympics, the lake was modified to accommodate the rowing events, which included dredging and the addition of specific infrastructure.
The lake is home to the Banyoles Bogatella, an endemic species of fish that is strictly protected.
Archaeological excavations have recovered well-preserved wooden tools and agricultural implements due to the anaerobic conditions of the lake's silt.
Lake of Banyoles is the largest natural lake in Catalonia and a significant karstic basin fed primarily by underground aquifers. It is internationally recognized for its Neolithic archaeological site, La Draga, which features the remains of one of the earliest sedentary farming communities in the northeastern Iberian Peninsula. The lake basin formed through the dissolution of gypsum and other soluble rocks, creating a unique hydrological environment. It served as the rowing venue for the 1992 Barcelona Olympic Games. The surrounding area remains protected, sustaining a diverse ecosystem of riparian vegetation and local fauna. Its water supply is remarkably stable, maintained by groundwater flow from the Alta Garrotxa mountains. The site provides tangible evidence of prehistoric construction techniques using wooden piles.
The elevated boardwalks and viewpoints at the southern end of the lake providing a panoramic view of the water and the surrounding Pyrenees foothills.
Walk the 8km perimeter path to access diverse viewpoints and quiet wooded sections away from the main town docks.
Check the La Draga archaeological park schedule in advance as it is not always accessible to the general public outside of guided tours.
Do not attempt to swim near the unmonitored shorelines or restricted ecological zones where deep-water currents exist.
Swimming is permitted only in designated areas; respect quiet zones near the nature reserve sections to protect local wildlife.
