Beneath the breath-taking natural phenomena of the Paklenica Canyon which is home to hikers, mountain climbers and bush walkers, a bunker from the 1950s is still in the renovation phase but is open to the public. At a depth of 80 meters, visitors can a face the man made rock climbing wall, watch some multimedia screens on tying knots, rock climbing and the park’s history, as well as see the work park rangers and rescue do before continuing on with their hiking journey.
