The Château du Clair de Lune hosts seminars, study days, gala dinners, product launches and weddings for up to 250 guests, with the Côté Terre event space, two smaller meeting rooms and 18 bedrooms. The hotel occupies a 19th-century house and its former hunting lodge in an eight-hectare park at 48 avenue Alan Seeger in Biarritz, a few minutes from the beaches and the town center.
Seminars and company events
The hotel sells study days and residential seminars. Its meeting rooms have daylight and wifi, and the eight-hectare park can host outdoor activities. Groups have two dining areas and a dedicated space for breaks. Beyond seminars, the team prepares offers to measure for birthdays, gala dinners, bar mitzvahs, product launches and showrooms.
The location suits teams arriving by train or plane: the hotel is 2 km from the station, 3.5 km from Biarritz-Anglet-Bayonne airport and 4.5 km from the center of Biarritz.
Weddings and receptions
The hotel has hosted weddings on the property for several years. The cocktail takes place on the château terrace and in the formal French gardens, or in the château salons for an extra charge. A covered walkway lined with wisteria leads through the rose garden to the Côté Terre reception building. The offer includes the room, its terrace and the pool for a brunch the next day, and a security agent who welcomes cars before the reception.
A wedding requires the private hire of the whole hotel, 18 rooms, for at least two nights, or three nights on long weekends and public holidays. The hotel shares its list of trusted suppliers, including caterers, florists, photographers and DJs.
Rooms and capacities
The Côté Terre building covers 350 square meters, with a caterer's kitchen, toilets and a reception area. The main room covers about 210 to 230 square meters and seats up to 180 people at dinner, or 250 with a paid extension. In theater layout it takes up to 250. A covered terrace of 120 square meters under a glass roof faces south, with a 180-degree view of the Pyrenees, next to a 15 by 5 meter pool.
Two rooms suit smaller meetings: the Bibliothèque Alan Seeger, 30 square meters for 12 people, and the Salon de Chambrun, 40 square meters for 26.
Accommodation
The 18 bedrooms are split between the château and the former hunting lodge. Some have a private terrace facing the gardens, others overlook the park. Rooms have air conditioning, a minibar and a Nespresso machine. A heated pool and a wellness area are on site.
Catering
The restaurant Marius stands on the property, in an 18th-century Basque farmhouse with a 180-degree view of the Pyrenees. It is run independently by Géraldine André and chef Sébastien Sanjou and serves bistronomic cooking from regional produce. For weddings, a caterer works from the Côté Terre kitchen, chosen with help from the hotel's address book.
History and setting
The house dates from the 19th century and stands in a park of old trees covering eight hectares, with formal gardens, a rose garden and a former hunting lodge. The avenue that leads to it bears the name of Alan Seeger, the American poet, also given to the library meeting room.
Getting there
The hotel is 2 km from Biarritz station, 3.5 km from Biarritz-Anglet-Bayonne airport and 4.5 km from the town center.
