Leave Zagreb’s bustling center behind, and explore some of the region’s most characterful and historical attractions, on this half-day, small-group tour. Set off in the morning following pickup from your accommodation. Travel first to the underground Markusevec bunkers, which were used in the Croatian War of Independence, before discovering an abandoned hospital in the middle of the forest. Then, continue to the medieval Medvedgrad Castle, located on Mt. Medvednica and built in the 13th century to protect against Tartar invasions.
