During the winter months, from mid-November to mid-May, Levi is Finland’s most popular ski resort with a total of 44 runs serviced by 28 lifts.

The Kittilä airport is a 15-minute drive away from Levi’s mountain village. An airport shuttle bus runs from the Kittilä airport to Levi after all scheduled flights. Taxis and car rentals are available at the airport.

Conference facilities, for the main event, include one auditorium and three lecture rooms, allowing 4 parallel sessions. In satellites, we have auditorium and one lecture room. We have modern easy to use conference equipment and high-speed communications, thus ensuring that meeting will run smoothly.

Childcare: Bayes Comp aims to be a family-friendly meeting. The target is to organise childcare. Due to limited resources, we encourage everyone planning to attend with kids, to contact Miracle Amadi (miracle.amadi@lut.fi) as soon as possible.
