Experience an original and unique group activity for half a day with Yllar. Challenge your teammates and office colleagues in tests of balance and reflection: like a Koh-Lanta adventurer, winter version. Search for the culprit and the identity of the victim in giant police investigations, in teams. Discover unique places and mountain villages on foot or by electric mountain bike during a discovery rally. Where to go? Activities for groups in Haute-Savoie (74) or Valais (Switzerland). From Lake Geneva to the snowy peaks of Châtel, we travel throughout the department and surrounding region. Chablais Massif, in France and Valais Switzerland. Example: Murder Party in Thonon-les-bains; Koh-Lanta parodies in Abondance and Châtel; Mountain bike rally in La Chapelle d'Abondance. Who is it for? Our fun challenges are for everyone. For individuals: alone, with family, with friends. Sign up for one of the dates proposed in the calendar. For your birthdays, bachelor parties, cousin parties etc...
