Round Birthdays

A round birthday is a moment that asks for more than a dinner reservation and a card. Forty, fifty, sixty, seventy: the numbers that mark a chapter deserve a setting that honours the person stepping into it. Altein, set between two alpine lakes at 1,800 metres in Arosa, is built for exactly that: a celebration where the room belongs to the guest of honour and every detail follows their lead. The format works as a long weekend, with arrivals on the Friday, the celebration dinner on the Saturday, and a slow Sunday before guests head home.

A weekend shaped around the guest of honour

A round-birthday weekend at Altein can open with arrival drinks at the Alchemilla Parlour Bar, alpine spirits and mountain botanicals setting a relaxed tone. The dinner itself can take place at Zus Brasserie for a warm, family-feeling supper, or at Alpensand, the rooftop restaurant, where the table is set against the surrounding peaks. The menu can be built around the celebrant's preferences, a custom cake brought out at the right moment, and the speeches timed so the room feels carried along rather than rushed. With 126 rooms across the property, the full guest list can stay under one roof.

Spaces for the celebration

Zus Brasserie seats up to around 200 for a privatised dinner. Alpensand seats around 80 around the panoramic windows. The Alchemilla Parlour Bar privatises as a late-night space for the closer guests. The restaurants at Altein privatise around the size and feel of the celebration, and the 950 m² spa is open to guests throughout the weekend.

Why Arosa for a milestone

At 1,800 metres, the air slows everyone down. The link to Lenzerheide opens 225 km of slopes in winter and 900 km of trails in summer; the spa, with indoor and outdoor pools, becomes the gathering point for those who would rather drift between the saunas than the slopes. A daytime activity gives the weekend a shared anchor before the dinner. A culinary hike with mountain huts and regional food along the way doubles as a moment for the closer guests to gather before the formal evening.

Planning your stay

We work with you on the round-birthday weekend from the date and the guest list outwards. Menus can be built around the celebrant's preferences. Surprises, a jazz trio, a quiet toast at the Alpensand windows after dessert, a slideshow, can be timed so the room is carried along rather than rushed.

Send us the date, the headcount, and a sentence about the person being celebrated. We will come back with a proposal that puts them at the centre of the weekend.
