You have to be a group of at least 8 people and you can be at most 22 people at the same time. There are toilets and a simple shower in a building next door. For those who wish, there is also a wood-fired sauna there, with lovely views of Siljan and the sunset.
Paintball must be pre-booked, as it requires an extra staff most of the time, as well as some preparation, etc. Booking by phone or mail.
