Mountain

Built between 1930 and 1933 by the forestry engineer Ante Premužić using local labour and hand-laid dry-stone construction, the Premužićeva Staza is one of Europe's finest mountain paths — 57 km of near-level ridgeline trail running along the crest of Velebit from Zavižan in the north to Baške Oštarije in the south, without ever exceeding a 10-degree gradient. It threads spectacularly through the karst forest of Rožanski and Hajdučki kukovi, a moon-scape of dolomite teeth and hidden dolines that would otherwise be impassable. The full traverse takes 3–5 days with overnight stops in the mountaineering huts of Alan and Ograđenica; sections can be sampled as day walks — the eight-kilometre stretch from Zavižan south to the striking Rossijevo Sklonište viewpoint is the classic taster and rewards you with a bird's-eye view over Rab, Krk and Cres. The trail is entirely waymarked with the traditional red-and-white targets and is exposed above the treeline, so weather-check before starting: summer thunderstorms roll in fast and shelters are basic. Wildlife you may cross paths with includes chamois, brown bear and golden eagle.

Nature Park

The most surreal landscape in Croatia lies at the heart of the Northern Velebit — a 12-square-kilometre labyrinth of grey limestone towers, sinkholes and karrenfields declared a Strict Nature Reserve in 1969. Named for the outlaws (hajduci) who once hid here from Ottoman patrols, the kukovi are a geological wonder: ice-age erosion has carved them into vertical needles of dolomite, some over sixty metres tall, spaced so densely that traversing the reserve off-trail is essentially impossible. Beneath your feet, the karst hides one of the world's most extreme underground systems — the Lukina Jama-Trojama pit, at 1,431 m the deepest cave in Croatia. Access is strictly limited: you can only enter along the Premužić Trail as it threads through the reserve, and camping, campfires and off-path walking are all forbidden. Come for the alien silence and the way the towers throw morning shadows like a stone forest of totem poles. Chamois and golden eagles are the reserve's most-seen wildlife; brown bear tracks appear regularly on the trail's dust. Bring good boots — the karst is razor-sharp and one misstep will slice a sole in half.
