These buildings are the origins of a former tile factory founded in 1850 by Charles Joseph Bertrand, which produced tiles of various designs for the entire region. Dauphiné roofs in the region are still covered with tiles made here. The location in Doissin was likely justified by the proximity of the clay that makes up the region's soil, the basic material for tiles. https://tuileriebertrand.jimdofree.com/ https://tourisme-valsdudauphine.fr/jy-suis/visites-et-patrimoine/musees/869960_ancienne-tuilerie-bertrand/

A very popular lake to visit during the summer months when the lake is quite refreshing. Every year, there is a time trial around the lake.

Very beautiful natural lake of glacial origin in the Chartreuse. The tour of the lake is about 17 kilometers through forest and fields, and allows you to admire the landscape from all angles.

Located at an altitude of 500 m at the bottom of a depression of glacial origin with a substantially north-south axis, the Etang du Grand-Lemps nature reserve presents an exceptional flora and fauna heritage over 53 ha. Its slopes are shared between pastured meadows, crops and chestnut copses. The bottom of the depression corresponds to a marsh covered by peat bog vegetation and phragmites. The peat environments, and more particularly the sphagnum groups, constitute the originality of the site. Source: Natural Reserves Org
