Built to host, like the inns of old

L'Arche de Thyra began life as a country auberge, and it still has the proportions of one: eleven private bedrooms, nine bathrooms and three large living rooms, with room for up to twenty-eight guests.
A wood fire in the main room, a high quality sound system, two large tables that seat all twenty-eight guests, indoors and out, a four-season spa, and a terrace that looks down over Lac des Sables.

The lake, from almost everywhere

Most bedrooms look out over Lac des Sables, three have their own balcony, and the upstairs living room opens onto Baie Major. The sun sets right across the water.

Eleven bedrooms

Each with a queen bed and grand hotel quality bedding. Eight of the eleven bedrooms have their own private bathroom; the three bedrooms of the suite share one large bathroom.
Five sofa beds join the queen beds to sleep up to 28.

Arrive as a group, leave as family.

Leadership retreats, launches, training days, year end celebrations: the house is yours alone, ninety minutes from Montreal.

Eleven private bedrooms, eight of them with their own private bathroom. Three living rooms for sessions and workshops, unlimited wifi and a 70 inch TV for presentations. And to celebrate: two large tables that seat everyone, indoors and out, a high quality sound system, the fire and the spa.

Tous les ans, on s'y réunit une vingtaine de personnes. C'est un endroit magnifique et parfait pour un groupe. […] Sinon, TOUT est toujours très propre. Les rénovations de la cuisine ont faites une belle différence cette année. J'ai hâte d'y revenir!!

Propre, spacieux, proche de tout (resto, bar, épicerie, plage etc.), la majorité des chambres ont leur propre douche et toilette, nous étions un groupe de 10 familles pour le weekend avec nos enfants. Pas mal d'espace rénovée avec du matériel moderne. Nous avons passé d'excellents moments. […]
