The Blue Line enters Croatia at the peak of Žbevnica on Ćićarija, from the direction of Slavnik in Slovenia. One available access option is to use the trail that begins at the cape of Savudrija and continues towards Žbevnica along the routes of the Istrian Hiking Trail (Istarski planinarski put), Parenzana
and the E-12 European Long-Distance Path.
Proceeding along Ćićarija and Učka,
Via Dinarica follows the route of the Istrian Hiking Trail
to Poklon and to the peak of Vojak, continuing across Ćićarija towards Matulji. What follows is a climb from Klana into the area of Obruč and Hahlić,
and the route then continues through mountainous terrain towards Platak, following the route of the Rijeka Hiking Tour
(Riječka planinarska obilaznica, RPO). From Platak, the route descends to Kamenjak, using a series of so-called senior trails towards the bay of Bakarski zaljev and towards the bridge Krčki most, taking hikers to the island of Krk. From Valbiska on the island of Krk, the trail continues towards Lopar on the island of Rab,
continuing further along a well-maintained network of attractive trails (Premužić Trail on the island of Rab, the Kamenjak area) towards the city of Rab. From the city of Rab, the Blue Line then takes us to Lun on the island of Pag,
continuing lengthwise across the island. The trail then touches the Paklenica National Park
and the border area of the Velebit Nature Park,
descending to the canyon of the Zrmanja River.
The section from the Zrmanja River to the city of Trogir is not mountainous in character, and it is ideal for a bicycle tour. In areas near the city of Šibenik (Vransko Jezero Nature Park, Krka National Park, the hill of Trtar), there are intriguing hiking sections. In the area above the bay of Kaštelanski zaljev, the trail follows the markings along Kozjak, partly using the route of hiking trails Cradle of Croatian Statehood and Solin Hiking Trail. Continuing across Klis, the trail proceeds towards the mountain of Mosor, passing it lengthwise to the area of Gata and Omiš in the canyon of the Cetina River. Given the fact that there is no longitudinal trail (along Omiška Dinara) in the section from Omiš to Gornja Brela, Via Dinarica is following the course of the Cetina River upstream towards Blato na Cetini, reaching Gornja Brela by road. The area of Omiš and the Cetina River offers ideal possibilities for various outdoor activities (rock climbing, rafting).
The section of the trail in the Biokovo Nature Park is over 100 kilometers long, and very demanding for hikers. This particular section is simply impassable without strong logistics and excellent fitness level. The core of this section is the Biokovo Hiking Trail, and a tour of this trail "in one go" is also colloquially known as the "Biokovo Wolf". Despite lower elevation, the southern part of Biokovo is also very difficult to pass through. From the lakes of Baćinska jezera, the Blue Line then descends to the city of Ploče.
The final part of the route continues along the Pelješac peninsula, starting from the town of Trpanj that can be reached by a ferry from the city of Ploče. Once on Pelješac, the Blue Line continues to the city of Orebić and to the peak of Sv. Ilija, following the cycling trail Maslina from Orebić to Ston. From there, a ferry takes visitors to the island of Mljet with excellent hiking infrastructure. This is where the corridor briefly takes the "opposite" direction, from southeast to northwest, by taking the route of the Mljet Hiking Trail from Sobra to Pomena, since that is the logical route direction on the island of Mljet. Pomena is also linked with the city of Dubrovnik by boat. Visitors interested in exploring the section from Dubrovnik to Konavle are recommended to tour that section by bicycle, since there is no suitable hiking infrastructure available in the area at this time. The mountain of Sniježnica offers remarkable views of the area of Konavle, which is where the Blue Line reaches the border of Croatia, Bosnia and Herzegovina and Montenegro, connecting with the Montenegro Hiking Tour on the mountain of Orjen.
