The tour lasts cca 5 hrs. Please, wear comfortable shoes and we advise you to dress in layers. We're not going to hike the mountain, but we're going into the forest at the bottom of the mountain and some parts of the terrain are uneven. It's always a few degrees colder in the woods. Please, make sure to put an insect repellent on, because the most dangerous animals in the forests of Zagreb are the smallest ones (especially ticks).
