Krupa Waterfalls: The Deveterac Vrela Terraces and the Monastery

Deveterac vrela — the nine springs, also written Bijeli buk — is the stretch where the Krupa breaks across nine travertine barriers, each throwing its own small waterfall, across roughly a hundred metres of channel just before the river meets the Zrmanja. The tufa grows the way it does across this karst: mosses and algae precipitate carbonate on the barriers, building white shelves that the water reorganises every flood season. Where the Krupa's own gorge narrows, the falls compress into one long white stairway; where it opens, they scatter into separate curtains between pools.

The setting explains the quiet. The whole stretch lies inside the Velebit Nature Park, whose managing institution documents the Krupa's cultural landscape — the falls, the old mills, the Kudin bridge — but builds nothing at the water. No road reaches the terraces, so the visitor numbers stay a fraction of the Plitvice boardwalks an hour east, and the people you meet arrive on foot or in kayaks. The Zrmanja below the mouth carries the big scenery: green water between limestone walls several hundred metres high in places.

The Krupa monastery stands on the left bank of the Zrmanja at the Krupa's mouth, in a gorge the founding monks chose for its isolation. Tradition dates the foundation to 1345, when monks came from the Krka monastery further south — which makes Krupa the oldest Orthodox monastery in Dalmatia and the second oldest in Croatia. The single-nave church is dedicated to the Assumption of Mary; the community kept an icon of the Virgin, credited with healing powers, from its earliest years. Ottoman pressure emptied the complex at times — it may have been abandoned by the mid-sixteenth century — but restorations after 1699 rebuilt the residence, and the stone bell tower of 1782 still stands over the gorge. The monastic community is small today; treat the place as a living site, not a museum.

On the Krupa itself, upstream of the falls, the Kudin bridge (Kudin most) carries an old track across the river on a line of low stone arches — the signature monument of the Krupa's cultural landscape and a good turnaround point for a walk that combines the bridge, the nine falls and the monastery in one loop.

• Monastery founded 1345 by monks from the Krka — oldest Orthodox monastery in Dalmatia.
• Bell tower completed 1782; church dedicated to the Assumption of Mary.
• Kudin most: the arched stone bridge on the upper Krupa, part of the documented cultural landscape.
• A modest, living monastic site — modest dress and quiet voices apply.

Swimming is lawful along this stretch — the Velebit Nature Park imposes no bathing ban on the Krupa or the Zrmanja canyon — and the pools between the tufa shelves are the natural bathing spots: clear, green, and shallow enough to warm in summer. Enter below the barriers where the current slackens, and treat the tufa as the fragile living structure it is: step on rock and gravel, not on the moss curtains that build the falls.

The calendar matters more here than at any big-name fall. After autumn and spring rain the nine barriers run as one continuous white stairway; by late July and August the karst sources shrink and the falls thin to trickles between pools — beautiful, but not the full staircase. The kayak season rides the same calendar: spring and early summer bring the best combination of volume and warm water.
