The minimum number of visitors is 8 people, and the maximum is 12. We remind you that the route inside is about 800 meters long in one direction. You can reach the Biserna cave on foot, as the forest road is not suitable for cars. Vehicles can be parked on the asphalt road before the turn for the villa of the Shumen Municipality. There are two walking routes - from the Kyoshkave park - "A lesson on the forest path" and from the junction for the "Old Town" Fortress on the road to the villa of the Shumen Municipality. Signs are placed along all routes.
The temperature in Biserna Cave is 10 degrees. Due to the high humidity and cave waters, tourists are recommended to wear suitable closed shoes and warm clothing.
Tourists will be accepted until November, as it is in accordance with the life cycle of the bats, whose habitat is the cave. During the cold months, the winged mammals hibernate to survive without food until spring, and disturbance during this period is prohibited.
