Zrmanja by kayak
Near Zadar the Zrmanja runs through a canyon 200 m deep; the half-day kayak safari (2,267 reviews) takes the small travertine drops at summer low water, and rafts run it in spring.

43° 27′ N · 16° 41′ E · From a glass ledge on Biokovo to the sea under Dubrovnik's walls · Ground 41
The Adriatic is flat.
The mountain behind it is not.
Biokovo rises straight out of the sea behind Makarska, and everything on these grounds hangs off that wall or the river that cuts through it. The Cetina leaves the karst at Zadvarje over a 55-metre waterfall, runs twelve kilometres of rapids and reaches the sea at Omiš under eight zipline wires. These grounds start on a glass horseshoe 1,228 m above the coast road, drop into the canyon on a cable and on a rope, and end twice at sea level: in a raft on the Cetina and in a kayak under the walls of Dubrovnik, two hours down the coast.

Stop 1 · Glass skywalk · Biokovo Nature Park, above Makarska
1,228M ABOVE THE SEA
The road climbs thirteen kilometres of hairpins from the sea, and at the Ravna Vlaška pass a glass horseshoe pushes eleven metres out over the cliff. You look down between your shoes at the Makarska Riviera, 1,200 metres below.

Two practice wires of 25 metres, then the real thing: eight cables down the Cetina canyon, 2,100 metres in all, the longest 700 metres and 150 metres up. Below you the water is green, the walls white, the wind real.

Stop 2 · Zipline · Zipline Croatia, Cetina canyon, Omiš
150M ABOVE THE CETINA

Stop 3 · Canyoning · Cetina canyon, Zadvarje
55M · THE GUBAVICA ABSEIL
The basic tour is swimming, sliding and jumps of up to ten metres through a canyon 150 metres deep. The extreme tour starts on top of the Velika Gubavica and lowers you 55 metres down the wet face of the falls.

Three hours down the canyon: easy rapids, long green pools, a cliff to jump from at three or six metres and a cave behind a waterfall that you swim into. Croatia's family river, and the most-booked thing on the Cetina.

Stop 4 · Rafting · Cetina canyon, above Omiš
0M · ON THE CETINA

Stop 5 · Sea kayaking · Pile bay, Lokrum & Betina cave, Dubrovnik
0M · UNDER THE CITY WALLS
You launch from the pebbles of Pile bay with Fort Lovrijenac over your shoulder and paddle along the base of the walls, 25 metres of stone straight up from the water. Then Betina cave for a swim, Lokrum, and back into the sunset.

Near Zadar the Zrmanja runs through a canyon 200 m deep; the half-day kayak safari (2,267 reviews) takes the small travertine drops at summer low water, and rafts run it in spring.
412 m above Dubrovnik, Srđ is the view everyone wants; the cable car of 1969 has run again since 2010. The walk on the walls – up to 25 m of stone, 1,940 m round – is the other way to see the roofs.
From Makarska, quad and buggy tours climb the Biokovo road to the Skywalk; behind Dubrovnik the ATV safaris run the karst above Srđ and the villages of Konavle.
Two hours north of Split the Velebit drops into the sea at Paklenica: Anića kuk, 712 m, with the 350-m wall of Brid Klina and more than 360 bolted routes – Croatia's climbing capital. No platform sells a guided day; only the park ticket is online.
Through a hole in the seaward wall of the old town, the Buža bars sit on the rocks where locals jump into deep water from a few metres up – unmarked, unguarded, at your own risk, and the best swim in Dubrovnik.

Zipline Croatia's course in the Cetina canyon, 3 km from Omiš, has eight wires with a total of 2,100 m; the longest is 700 m and runs 150 m above the river at up to about 70 km/h. The whole tour takes around 2.5 hours with two guides, from age 7 and up to 140 kg. About €80 on GetYourGuide or Viator, with pick-ups from Split.
The Skywalk stands at 1,228 m on the Ravna Vlaška pass, 13 km up the Biokovo road from the coast, about 6 km east of Makarska as the crow flies. Private cars need a timed park permit; easier are the tuk-tuk, buggy or minibus tours from Makarska for €45–59, which include the ticket and skip the queue at the gate.
Basic is 2–2.5 hours of swimming, sliding and optional jumps of up to 10 m through the 150-m gorge near Zadvarje, from about €50. Extreme adds ropes: a 55-metre abseil down the face of the Velika Gubavica waterfall and a second abseil of about 25 m, roughly 4 hours, from about €60–80. Both start in Zadvarje with pick-ups from Split and Omiš.
Yes – the 12-km stretch is class II–III, about three hours, and the operators take children from about five with a parent. The cliff jumps (3 or 6 m) and the swim into the cave are optional. Season April to October; the water is cold even in August, wetsuits are usually included.
About 5 km in 2–3 hours: from the beach in Pile bay under Fort Lovrijenac, along the base of the city walls to Betina cave for a 20–30-minute swim and snorkel, round Lokrum island and back. No experience needed, double kayaks. Sunset departures are the popular ones; the leading tour has more than 4,400 reviews.
