On the third day, the route begins at the Parish Church of St. Martin—one of three medieval parishes (first mentioned in 1334) that existed in the area of ​​the present-day City of Karlovac. The route follows a gravel road along the banks of the Kupa River all the way to the City of Alessandria Bridge in the center of Karlovac. After crossing the bridge, the route continues along a landscaped riverside promenade to the Karlovac Brewery, where the ascent toward the Old Town of Dubovac—once an estate of the noble Frankopan and Zrinski families—begins. Next to the Old Town (eighth stamp) lie the foundation remains of the Church of St. Michael, the center of the medieval Dubovac parish, also mentioned in 1334. The route then descends past the modern-day Parish Church of Our Lady of the Snows to the National Shrine of St. Joseph (ninth stamp), which also holds the status of a minor basilica.

The route then proceeds along Marmont Avenue—part of the historic Lujzijana Road—and Maček Street to the start of the Korzo and the “Karlovac Milestone.” Afterward, it continues along the Dr. Franjo Tuđman Promenade (known locally as the “Promenada”), passing the Music Pavilion, the Edison Cinema, and the historic “moats,” to the beginning of Radić Street and the Katzler Pavilion (tenth stamp). The route enters Zvijezda—the historic center of Karlovac and the world’s first realized ideal Renaissance city—through the Rijeka Gate. It continues to the Church of the Holy Trinity (the main altar features a statue of St. James, commemorating the medieval church and parish that partially overlapped with the territory of the current Holy Trinity parish) and Ban Josip Jelačić Square. The route then proceeds via Ruski Put and Vrbanić Park to the banks of the Korana River. There, pilgrims can choose to cross the Korana via either the “Wooden Bridge” or the “Pontoon Bridge” before following a landscaped promenade to Aquatika – the Karlovac Freshwater Aquarium (eleventh stamp).

After Aquatika, the route crosses the Korana again and turns past the Foginovo bathing area toward the Karlovac Gymnasium (where Nikola Tesla attended school) and the Nikola Tesla Experience Center (twelfth stamp). It then continues through the Rakovac district along the Korana riverbank to the Alley of Croatian Defenders, where it enters Mostanjsko Polje. The route continues along the embankment beside the Korana and Mrežnica rivers, passing the confluence of the Mrežnica and Korana, all the way to the bridges crossing these rivers. After crossing the Korana, the route enters the settlement of Turanj; the Karlovac–Turanj Homeland War Museum (thirteenth stamp) is located at its entrance, marking the end of Day 3.
