In Ljubljani and in Kranju there is a number of indoor climbing walls. We visited Climbing center Ljubljana. It was fun.
Climbing center Ljubljana is a modern indoor rock climbing and bouldering gym, located in the greener part of the Štepanjsko naselje area in Ljubljana. Established in December 2013, the center is designed exclusively for sport climbing and related activities. It is the largest state-of-the-art sport climbing facility in Slovenia, offering 1280 m2 of climbing surface including a high wall (up to 17 metres) and boulder with a variety of problems and grades. Whether you are a climbing addict, a competition climber or a newbie, Plezalni center Ljubljana is definitely the place for you!
