With their height and length, the Dinarides represent a sharp wall preventing the penetration of the Mediterranean influences into the hinterland. Despite abundant precipitation at the boundary of the two climatic regions, there are very few surface watercourses, and water quickly disappears in karrens, abysses and underground cavities. Visitors of coastal mountains must bear in mind that hilly areas along the sea are not as fresh as high mountain areas, so it is better to avoid difficult climbs during the summer period. In addition, bora wind can be quite unpleasant, and even dangerous in strong gusts. The ideal seasons for exploring the Blue Line of Via Dinarica in Croatia are late spring and autumn.
With the exception of the Biokovo Nature Park, the Blue Line of Via Dinarica has no demanding or extremely hard routes. This longitudinal tour enables hikers to explore amazingly diverse coastal areas and their interesting karst characteristics.
