Venture across the border to explore majestic sites of Bosnia and Herzegovina. In Počitelj, admire the stunning Ottoman architecture on the banks of the river Neretva. In Mostar, a literal crossroads between the east and west, marvel at the 16th-century Old Bridge and stroll around the charming Old Town that will lure you with its shops, restaurants and cafes. After lunch on your own, head to Međugorje. This religious pilgrimage site became world-known after reports of apparitions of the Virgin Mary by six local children. You can climb Apparition Hill, attend a mass at the local parish church, or simply wander and explore the town.
