Sport climbing is an increasingly popular sport. An extension to the elementary school Lava was built in 2009, housing a sports climbing wall. Recreational climbing, beginner courses, and advanced courses are offered for the youngsters. Upon completing the course, children are presented the title of sport climber which is a requirement for climbing at organized crags.

Competitors of ŠPO – PD Celje Matica (Hiking Society Sport Climbing Section) hold training sessions on the modern wall of the Lava gym, renovated and extended in 2012. The wall is suitable for practice for the best sport climbers, as witnessed by its use by the bouldering world championships runner-up Jernej Kruder and his younger sister Julija who also ranks among the top climbers in her category at international competitions.
