Underground wine boat trip

The underground lake at Saint-Léonard is the largest in Europe that can be explored by boat. Let multilingual guides take you on a journey of discovery through this fascinating universe. During a 30-minute guided tour, you’ll glide over the calm waters of the lake as you sip on wines from our Belle Etoile range, accompanied by nibbles. Then it’s on to Castel d’Uvrier, Provins’s gourmet restaurant in the heart of the vineyards, to enjoy a delicious, seasonal, three-course meal created by Bruno Toppazzini (13 points in Gault & Millau 2017).
