A raw wind cuts across the open pass as the trail climbs away from the Piva reservoir; stony switchbacks push hikers into an alpine bowl, and below, Trnovačko Lake sits like a piece of sky spilled into the mountains. The route rewards persistence with a sudden clearing where the lake’s heart-shape and turquoise water appear framed by serrated limestone ridges and forests that push their shadows to the shore.

History
The Dinaric Alps were uplifted by tectonic collisions that shaped the region; local highland communities historically moved seasonally with flocks, leaving stone cabins and trails still in use.
Conservation
Alpine meadows and karst ecosystems are fragile—stick to trails, pack out waste, and avoid disturbing grazing areas and rare plants.

Start at first light
Begin from Plužine early to avoid afternoon storms and give yourself the full daylight window for the 8–10 hour route.
Footwear matters
Wear grippy, ankle-supporting boots — the ascent and descent include loose rock and steep sections where traction prevents slips.
Cold water caution
The lake is fed by mountain runoff and stays cold year-round; limit swimming time and dry off quickly to avoid hypothermia.

Stay on durable trail sections and avoid trampling alpine meadows that local shepherds use for summer pastures.
