An agreement on cooperation between four ski centers was signed on our Jahorina – Jahorina, Bjelasnica, Ravna planina and Vlasic. The agreement is reflected in a unique map that is valid for skiing on over 100 km of trails in these four ski centers. It is a ticket 10 in the season that can be purchased and used in all four ski resorts. The ticket price is 350 KM and is valid for any 10 days until the end of the winter season. The user can ski one day on Bjelasnica, and the next day on Vlasic, Ravna Planina or Jahorina. The common ticket 10 from the season is valid until the end of the winter season 20/21, for 10 days of skiing that do not have to be used continuously and the skier has the opportunity to choose how many days he will ski at one of the four ski centers.
