Domaine les Ranchisses can host a seminar, a convention or a wedding for up to 350 guests, with lodging, meals and activities on the same site. The family estate covers 30 hectares in Chassiers, in the southern Ardèche, on the banks of the Ligne river and inside the Monts d'Ardèche regional nature park.
Seminars and company events
Five modular spaces serve plenary sessions, workshops and meals, and the largest takes 350 people. The rooms receive daylight and open directly outside for breaks and cocktails. High-speed Wi-Fi, video projectors, paperboards, a sound system, tables and chairs are provided. Groups can add team activities from a list of more than 20, including canoeing, canyoning, padel and paintball, as well as time at the spa. Catering and accommodation can be combined in one quote, with half-board, a welcome drink and a closing dinner. The whole estate can be privatized outside its public opening periods.
Weddings and receptions
The estate has a dedicated wedding offer, and guests who come for the weekend can sleep on site in cottages or hotel rooms. A wedding brochure details the accommodation options. For a large wedding, the plenary room takes up to 350 guests and the restaurant seats 250.
Rooms and capacities
The five reception spaces can be arranged to suit the format of the event. The plenary room takes up to 350 people and the restaurant seats 250. All spaces have natural light and direct access to the grounds, which helps for coffee breaks outdoors and evening cocktails.
Accommodation
Hôtel Les Vignes, a three-star hotel on the estate, has 12 rooms, two of them adapted for guests with reduced mobility. The estate also offers cottages for two to six people, Tribu and XXL cottages for large families or teams, Le Mas d'Alice and a gîte. The site counts about 200 lodgings in total. In season, the estate also runs as a five-star campsite in the Yelloh! Village network.
Catering
L'Auberge des Ranchisses serves Ardèche cooking at lunch and dinner, including charcoal-grilled meats and wood-fired pizzas, indoors or on a shaded terrace. Group menus are composed for each event. A bar and a small grocery shop complete the offer.

The Ardèche gorges and the Chauvet 2 cave replica are within reach for a group outing.
