You can leave your bikes at the top of the cliff and descend into the coves along Bordardoué beach. You can observe some very beautiful rock structures, notably the folded schists, which present a superb millefeuille alternating light-colored sedimentary deposits and dark volcanic ash. Everything has been annealed and folded in depth over the geological ages.

The Aiguade was built in 1696 to collect water from a spring and provide drinking water for the king's ships. It was probably Vauban, Louis XIV's great military engineer, who took the initiative to build it during his stays on Belle-Île (between 1683 and 1689). This is why it is also called the Aiguade Vauban. Together with the Royal Fountain of St-Nazaire near Rochefort, the Belle Fontaine is the only building still standing in France! It was the first building on the island of Belle-Île to be listed as a historical monument in 1993. The reservoir, with a capacity of 850,000 litres, is 22.5 metres long, 6.5 metres wide and 6 metres deep. It is protected by a stone arched vault whose reflection in the water gives the impression of a cylindrical structure. From a small terrace, you have a beautiful view over the small bay where ships used to anchor and send their shallow-draft dinghies to the Aiguade to take in the water. In 2012, the entire ensemble was completely renovated. Several panels provide information about the history of the building.
