Introduction
Lika-Senj is Croatia's least densely populated county, a landscape of karst mountains and forest that holds the country's single most-visited inland attraction, Plitvice Lakes National Park, alongside a wild mountain interior and a short stretch of Adriatic coast around the historic town of Senj.
Overview
Lika-Senj sits inland and mountainous for most of its territory, its sparse population and dense forest giving it a genuinely different character from Croatia's crowded coastal counties. Its centrepiece, and the reason most visitors come at all, is Plitvice Lakes National Park — a UNESCO World Heritage site of sixteen turquoise lakes connected by waterfalls, strung together through beech and fir forest and explored on wooden boardwalks that put visitors directly over the cascades. Beyond the park, the county holds the northern reaches of the Velebit mountain range, Croatia's longest and one of its wildest, protected as a nature park and popular with serious hikers rather than casual visitors. On the coast, the small town of Senj carries a genuinely distinctive history as the base of the Uskoks, Habsburg-era pirates and irregular fighters who used the town's fortress and the notorious local bura wind to their advantage against Ottoman and Venetian shipping alike. Inland near Gospić, the village of Smiljan holds the birthplace and childhood home of Nikola Tesla, now a small museum. Lika-Senj rewards a slower pace than the coast — fewer crowds, cooler mountain air, and a genuinely rural character.
Discover Lika-Senj
Plitvice Lakes National Park's sixteen lakes owe their vivid turquoise and green colours to the same process that built the lakes themselves: dissolved minerals in the water, mainly calcium carbonate, precipitate out and form travertine barriers as the water flows downhill, and these natural dams are what create the lakes' stepped, cascading structure in the first place. The mineral content also scatters light in a way that shifts the water's colour depending on the concentration of algae, minerals and the angle of sunlight, which is why the same lake can look a different shade of blue or green from one visit to the next. The travertine barriers themselves are still actively forming today — the park is, in a real sense, a landscape still under construction rather than a fixed, finished formation.
