1 Nuitée dans l' écolodge Les Carrelets Graves & Sauternais Imagined like the carrelets (fishermen's huts on the banks of the Garonne), eco-lodges are invitations to relaxation and serenity. With friends, family, golfers or just for a night, you can experience a unique moment in one of the 9 eco-lodges located on the shores of Lac des Graves & Sauternais.
