Lac d'Ilay

-

Lake of Ilay is a natural lake of icy origin with a wild appearance. This lake will surprise you with its turquoise coloured shores on a clear day and its cliffs in the background.

It is also called the Lac de la Motte because it has the particularity of having an island or motte.
The island was connected to the land by a causeway, now submerged, but whose trace can be followed by the rushes that cover it.
Archaeological excavations show that the island was already inhabited in the Neolithic period, and a monastery was established there around the year 1000, the "Saint-Vincent Priory".

With a very elongated shape and a surface area of 72 hectares and an average depth of 10 m, it is mainly fed by the Grand Maclu lake, to which it is connected by a small natural canal of about 200 metres.
The lake of Ilay flows into the Hérisson river.

Possible activities :
Hiking (tour of the 3 lakes / 4 lakes) and mountain biking (tour of the 5 lakes), horse riding, activities and entertainment offered during the holidays ...
