Marcieux is the smallest in number of inhabitants of the 11 communes of the Community of Communes of Lake Aiguebelette with barely more than 200 inhabitants. Located 6 km from Lac D’Aiguebelette, between 500 and 1450 meters above sea level. The climax, Château-Richard, may be the goal of a hike to the top of L’Epine which will allow you to reach points of view on the two lakes of Aiguebelette and Bourget.
