Private Parties

The best private parties have a personality. A surprise fortieth disguised as a quiet weekend in the Alps. A friends' costume night that finally happens after years of "we should". A reunion of a university group, twenty years on, with the same people who were impossible together then somehow more impossible together now. Hosting a private party in Arosa needs a venue willing to play along, flexible enough to lean into the brief, and disciplined enough to make the brief actually happen. Altein, at 1,800 metres between two alpine lakes, is set up for exactly that kind of evening.

Spaces for the celebration

Three rooms carry the format. The Alchemilla Parlour Bar privatises into a late-night cocktail bar with a dedicated bartender and a music brief built around the night's theme, suited to costume parties, decade nights, and after-dinner extensions. Zus Brasserie hosts the longer, more relaxed dinner where the conversation runs longer than the courses and transitions smoothly into dancing if the night wants to go in that direction. Alpensand, our rooftop restaurant, is the room for evenings that want a more dramatic frame: birthdays where the lighting matters, themed dinners where the staging is part of the joke, surprise reveals where the panoramic windows do half the work. Full details on the private F&B spaces at Altein.

A weekend shaped around the brief

Themes are taken seriously at Altein. Murder-mystery nights, seventies and nineties revivals, white-tie soirées, casino evenings, and surprise birthdays are all part of the repertoire. The kitchen builds menus around the theme, the bar develops cocktails to match, and playlists are tuned to the room rather than pulled from a default list. Dietary requirements (vegetarian, vegan, gluten-free, allergen-aware) are built into the menu from the start. Surprise logistics, hidden cake arrivals, discreet guest transport, and the small protections that keep a surprise actually surprising are handled quietly in the background. A daytime activity adds a second register to the visit. See the full list of Arosa activities, from culinary hiking to wild herb foraging.

Why Arosa for a private party

A private party in a home city carries the gravity of weekday life: work calls in the morning, children peeking in, the evening winding down because everyone has a commute. A private party in Arosa has none of that. Guests arrive on the Friday or Saturday morning, the village itself is the destination, and the evening can stretch as long as the group wants because nobody is going home until breakfast. The property has 126 rooms, so guests stay over and walk to breakfast at Zus Brasserie the next morning rather than ordering taxis at midnight. The 950 m² spa is open through Sunday for the inevitable slow recovery the next day.

Planning your stay

Private parties at Altein are planned without flattening the brief. We work with you to define what the night should feel like, louder, quieter, weirder, smarter, and shape the food, drink, music, and staging from that single answer.

Send us the date, the headcount, and a paragraph on the personality of the night. We will respond with a proposal that matches the brief and protects the surprise where it matters.

Frequently asked questions

How many guests can Altein host for a private party?

Up to around 130 across the connected Zus Brasserie and Alchemilla space, around 80 standing at Alpensand, and around 50 in the privatised Alchemilla Parlour Bar. Larger groups can spread across multiple spaces with a co-ordinated flow.

Can the venue be privatised for the evening?

Yes. Alchemilla, Zus Brasserie, and Alpensand each privatise individually, and the full F&B floor can be taken over for larger parties.

Can themed evenings and dress codes be supported?

Yes. Murder-mystery, decade nights, white-tie, casino evenings, and surprise birthdays have all been hosted at Altein. Menus, cocktails, and playlists are built around the brief.

Can the party run into the next day?

With 126 rooms on site, guests stay over and breakfast is served at Zus Brasserie the next morning. The 950 m² spa is open for the slower recovery day.

How far in advance should we book?

It depends on the season, but the earlier the better. Peak periods (December to March, July to August) fill first, and shoulder-season dates can often be booked at shorter notice. Send us a request with your preferred date and we will come back with availability.
