Plaža Žusterna, Koper: A Motorway Tunnel Quietly Handed Five Kilometres of Coast Back to People Instead of Cars

Slovenia | Žusterna | Koper, Slovenian Istria

The coastal motorway connecting Koper and Izola was extended through a tunnel, and the road that used to run along this exact shoreline simply stopped being needed for cars. The result was four to five kilometres of newly accessible coastline, handed over to people rather than traffic, with Žusterna sitting right at the start of it. I find this kind of quiet, practical urban-planning win more interesting than most of what gets marketed as a beach’s main attraction.

Koper itself, a short walk away, carries a name history considerably more layered than most visitors realise. The original Greco-Thracian settlement was called Aegis; the Romans renamed it Capris; under Byzantine rule it became Insula Capraria — literally Goat Island, since it genuinely was an island at the time — and later Justinopolis. The Venetians, who left the deepest architectural and cultural mark on the town, renamed it Capo d’Istria, Head of Istria, the source of the modern name Koper still used today. A walk to the Taverna, once a salt warehouse, traces the town’s long history of salt production, and the case a ghëto houses on Kidričeva street show a distinctive blend of local, oriental, and Venetian architectural influence, their upper storeys leaning out on wooden support beams.

Getting There: 15 to 20 Minutes on Foot From Tito Square, or via the H6 and the Žusterna Exit

From central Koper, the flat, scenic pedestrian and bicycle path along the coast covers the distance from Tito Square in about fifteen to twenty minutes, an easy walk or a short cycle. By car, the H6 regional highway between Koper and Izola has a dedicated Žusterna exit just before the tunnel — worth watching for closely, since one local account specifically warns that if missed, the next reasonable option is to continue through to Izola and circle back, adding roughly ten minutes rather than turning around mid-tunnel. A large car park sits directly behind the beach, though it fills quickly on weekends and isn’t free. Koper’s local bus lines 1, 2, and 5 also stop at Žusterna, a two-minute walk from the entrance.

The Beach: Free Concrete and Gravel, a Separately Ticketed Pool, a Dog Beach Nearby

Žusterna itself is free to enter — concrete sunbathing platforms, grassy lawns, and gravel sections with metal ladders for direct sea access, holding Blue Flag certification for water quality. I want to correct an impression some descriptions leave: the adjacent Olympic-sized pool, part of the Aquapark Žusterna complex, is a genuinely separate, ticketed facility rather than something included with the free beach, and at least one account notes it closes as early as 4pm — worth checking current hours before planning a day specifically around it. Trees along the back of the beach provide shade, a small beach bar serves refreshments, and an inflatable water park operates for children in the summer months.

I should also flag, since dog-friendly beaches come up regularly along this coast, that the main Žusterna beach itself does not allow dogs. A separate cove nearby, Pasja plaža Žusterna (Žusterna Dog Beach), part of the same coastal park, is specifically set aside for visitors with pets, leashed but free to swim and play within the designated section.

Plaža Žusterna, west of Koper, sits along coastline only freed for pedestrian use after a motorway tunnel rerouted traffic away from this stretch of the shore. Koper itself carries a name history running through Aegis, Capris, Insula Capraria (Goat Island), and Justinopolis before the Venetians renamed it Capo d’Istria. The beach is free, concrete and gravel, Blue Flag certified, with a separately ticketed Olympic pool nearby that closes relatively early, and a dedicated dog beach just along the same coastal park since the main beach itself doesn’t allow pets. Fifteen to twenty minutes on foot from Tito Square, or via the H6 and the Žusterna exit before the tunnel. For more of this coast, Svetilnik Beach Izola Slovenia is a short distance further along.

Walk or cycle from Tito Square along the new coastal path. Watch closely for the Žusterna exit before the tunnel if driving. Check the pool’s hours separately if that’s part of the plan, and use the dedicated dog beach nearby if travelling with a pet.
