Lac d'Ilay


Lake Ilay is a natural lake of glacial origin with a wild appearance. This lake will surprise you with its turquoise-coloured shores on a clear day and its cliffs as a backdrop.

The lake is also known as Lac de la Motte, because it has an island or motte.
The island was linked to the land by a causeway, now submerged, but whose traces can be traced by the rushes that cover it.
Archaeological digs have shown that the motte was inhabited as far back as the Neolithic period, and a monastery was established there around the year 1000, known as the Saint-Vincent priory.

With a surface area of 72 hectares and an average depth of 10 metres, it is fed mainly by the Lac du Grand Maclu, to which it is linked by a small natural canal some 200 metres long.
Lake Ilay empties into the Hérisson river.

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