Lokrum island beaches: what to swim in and where to lie

Swimming on Lokrum: a different experience

Lokrum’s swimming is not beach swimming in the conventional sense. The island has no sandy coves, no imported sand, and no beach clubs. What it has is a rocky coastline of smooth limestone ledges that make perfectly good sunbathing platforms, a sheltered saltwater lagoon that is one of the most popular swimming spots in the Dubrovnik area, a naturist section (FKK) for those who prefer to swim without swimwear, and the kind of crystal-clear water that comes from an island surrounded by open Adriatic on three sides.

The character of swimming on Lokrum is also shaped by the island’s status as a nature reserve. No development means no sunbeds for hire (except on the ferry jetty side), no beach bars, and no plastic chairs blocking the best rocks. You find your own patch of limestone, put your towel down, and you have it. The peacocks that wander between the trees are unimpressed by tourists and will sometimes attempt to eat your lunch.

The Dead Sea (Mrtvo more)

The Dead Sea is a natural saltwater lagoon on Lokrum’s southern coast, connected to the open sea through a narrow rocky channel. The name comes not from any salinity difference (it’s the same Adriatic salt water) but from the stillness — sheltered from wind and wave, the surface is usually glassy even when conditions outside are choppy.

The lagoon is shallow (1–2 metres) and warm — often warmer than the surrounding sea because the enclosed basin heats up in the sun. The bottom is flat rock and visible from above. The entry is gentle: you step down from the rocky edges rather than diving in, which makes it ideal for children and non-confident swimmers.

In peak season, the Dead Sea gets busy — most families visiting Lokrum end up here because the access is easy from the main path. Arrive before 10:00 to claim a good spot on the surrounding rocks.

FKK area

The FKK (Frei Körper Kultur — free body culture, i.e., naturism) area is on the eastern coast of Lokrum, reached by a path from the main jetty area that takes about 15 minutes. It is a designated naturism section with flat limestone ledges and direct access to the open Adriatic.

The FKK area is specifically for full nudity (swimwear is not required but is also not prohibited). It attracts a mix of regular naturists and curious first-timers. The swimming from the ledges is good — deeper water and cleaner than the more sheltered areas of the island.

Non-naturists who end up walking to this area by mistake are welcome to stay or to backtrack — the path is well-marked.

Rocky ledges and open-water swimming

The western and northern coasts of Lokrum face the open Adriatic and have smooth limestone ledges at various heights above the water. These are the spots that experienced open-water swimmers seek out — the water is deeper, the visibility better, and the freedom to jump in from different heights is part of the appeal.

The area around Betina Cave on the northern coast — accessible by kayak or a longer walk — is particularly good for snorkelling from the rocky platforms. See the kayaking Lokrum and Betina Cave guide for the full picture of this coastline.

Caution: The western and northern ledges face open water and are exposed to swell. In calm summer conditions they are safe for experienced swimmers; in any significant wind or after poor weather, the surge against the rocks makes entry and exit difficult. Assess conditions before jumping in.

What to bring to Lokrum

• Water and food. The island has a café near the monastery ruins but otherwise no facilities. Pack enough for the day, particularly if you’re coming in July heat.
• Snorkelling gear. The visibility around Lokrum is excellent and the outer coast has varied marine life. Bring a mask if you have one.
• Water shoes. Entry into the water from the limestone ledges benefits from rubber-soled shoes.
• Shade. The walking path areas have tree cover but the ledges are exposed. A hat and sunscreen are essential.
• Cash. The café on the island may not accept cards. Bring euros.

Getting to Lokrum and planning your visit

The ferry from the Old Port runs roughly every 30–45 minutes in summer. The last return ferry typically departs Lokrum around 20:00 — check the current schedule before your visit, as times change seasonally. The crossing takes 10 minutes.

Allow at least half a day on the island — two to three hours if you’re just swimming, four to five hours if you want to walk the paths, visit the monastery ruins and botanical garden, and explore the outer coast.

Frequently asked questions about Lokrum beaches

Can you camp on Lokrum overnight?

No. Lokrum is a protected nature reserve and overnight stays are not permitted. The last ferry back to Dubrovnik leaves in the evening and all visitors must depart. There have been historical incidents of people being marooned on the island (which gave rise to a local legend about a “curse of Lokrum”) — do not miss the last ferry.

Is the Lokrum ferry reliable?

Yes, in summer. The service runs regularly and times are posted at the Old Port pier. In bad weather (strong wind or rain), the ferry may be delayed or cancelled. Check conditions before committing to a full day on the island in uncertain weather.

How does the Dead Sea compare to regular sea swimming?

The Dead Sea lagoon is calmer and warmer than open-water swimming but less dramatic. Some swimmers prefer the stillness and shallow depth for relaxed floating; others find it too enclosed. Most people who visit Lokrum use both — the Dead Sea for family swimming and relaxation, and the outer ledges for a proper open-water swim.

Is the FKK beach popular?

Yes, in summer. It has a loyal regular clientele among both local naturists and visiting Europeans for whom naturist swimming is normal. It is not exclusively for elderly naturists — it is used by all ages. There is no social pressure either way; you swim in whatever you prefer.

Are there sea urchins in the Lokrum swimming areas?

Yes, as throughout the Adriatic rocky coast. They are visible on the rock surfaces (dark spiny spheres) and are easy to avoid if you look before entering the water. Water shoes eliminate the risk almost entirely.
