Swimming the Croatian islands near Sibenik, Croatia

Croatia has over 1000 islands and is widely known as a popular travel destination. Many come to Croatia in the summer months for sailing or family holidays, but we focus on the best swimming locations in Croatia. The water temperatures in the Adriatic sea, lakes and rivers reach up to 25C in the summer and this offers several opportunities for swimming.

Criteria for best swimming locations in Croatia

We have a long history of running our guided swimming holidays and we have researched and tested several of the best swimming locations in Croatia from south to north. During the summer months from June to September, several bays, ports and coastlines become significantly busier with boat traffic which puts swimmers at higher risk when in the water. Despite Croatia being under EU maritime laws, we hear that boat accidents happen every year.

Before getting into any water for a swim, we recommend you know your limits and take appropriate safety precautions. Check the weather before-hand, stay close to the shore, be aware of boat traffic and other hazards, wear bright hats and use a tow float for extra visibility to boats. For optimum safety and peace of mind, join an organised Croatia swimming holiday.

We have used the following criteria when putting together below the best swimming areas in Croatia

Access: how can you get to these locations, – Boat traffic: how busy the area is and what potential hazards you could face there,

Swimming options (coastline, bays, island hopping): where can you swim and are there any wind-sheltered options, tides,

Self-supported swimming option: can you swim there on your own or do you need an escort (boat, kayak, sup).

Facilities: What facilities are there, any hotels, restaurants, bars, tourist attractions, boat, kayak or SUP rentals.

Cost: most areas are free of charge while others require an entry fee (National parks).

Best swimming locations in Croatia

We have chosen to rank our locations from Southern Dalmatia to Northern Dalmatia and Istria. The reason for this is that there is a lot less boat traffic in the south compared to the north. Many visitors to Croatia come from mainland Europe and they are also the main boat users in the northern part. As well as that, more Croatians live in the upper part of the country.

Lastovo archipelago is the youngest national park in Croatia. The area contains 46 islands, rocks, reefs and cliffs and it is the southernmost Croatian populated island. It takes about 4 hr to get there by ferry from Split. Due to its remote location, the whole area is never too busy with boat traffic and it is safe to swim at several places.

This area is well protected from strong winds and rough sea providing the best venue for a safe swimming environment.

Krka River national park is one of the busiest parks in Croatia hosting thousands of guests every day in the summer. You can swim in the river at Skradinski buk under the waterfalls, however, there is an area marked zone for swimmers which means you can only swim around a little bit with other people.

You will feel the freshwater tiny bit of salt from the river estuary. The summer water temperatures go up to 25C.

7. Kornati National Park

Kornati islands are considered some of the most beautiful sailing areas in the Mediterranean and only accessible by boat. An archipelago consists of over 140 islands and islets covering a large area of over 30 km. There are two access points: Vrata od Opata and Velika Proversa strait. Due to its remote access, not many daily boats reach this area from the mainland which makes a special place for adventure swimming and exploring.

The best way to explore the range of islands is by boat where you can liveaboard there for several days as you navigate through. You can swim more or less anywhere between the islands or coast, considering the boat traffic and anchorage bays. We advise having an escort with you as there aren’t many facilities around. You need to pay an entry fee per day for either a boat or individually. Fees are from 125 Hrk (15 Euro) to 600 Hrk (80 Eur) per day.

Access: by boat only. Boat traffic: mid-level in the summer, otherwise low. Swimming options: island-hopping, bays and coastal. Self-supported: you can swim in bays or coastal on your own (mornings, evenings), but we recommend an escort for any other swims. Facilities: low-range (apartments, hotels, restaurants, beach, bars). Cost: see above.

8. Telascica National Park

Telašćica park is located next to Kornati islands on Dugi island in the north-west and sailors often describe this park as the safest natural harbour for anchoring.  We recommend swimming inside the Telašćica bay area where it is usually very sheltered from any wind conditions. However, if you want to swim along the steepest white Adriatic cliffs then you will need to head outside of the bay in the open Adriatic sea. This only is recommended when the sea conditions are flat and you have a suitable boat escort with you.

Access: by boat only. Boat traffic: mid-level in the summer. Swimming options: bay and coastal. Self-catering: you can swim in the bay or coastal on your own (mornings, evenings), however, we recommend an escort for any other swims. Facilities: low-range (apartments, restaurants,).

Brijuni islands are part of the National Park which are located just a few kilometres from the town of Pula in Istra. Istra is known as the largest peninsula within the Adriatic sea in northern Croatia. The whole park has strict rules about what can you do and where can you swim. Bathing and swimming are only allowed in the designated areas, but overall, this offers a wide range of locations in the park. In the summertime, several daily boats come from Pula around 10-11 am and leave in the afternoon. To avoid having other people around, the best time for a proper swim is in the morning or in the afternoon.

Access: by boat only from Pula. Boat traffic: mid-level in the summer. Swimming options: bay and coastal in marked areas. Self-catering: you can swim in bay or coastal on your own (mornings, evenings), but we recommend an escort for any other swims due to boat traffic. Facilities: low-range (only small restaurants).

10. Kolpa River (Risnjak National Park)

Kolpa river sources in Risnjak National Park and flows all the way into the Sava river. The river forms a natural border between north-west Croatia and south-east Slovenia.

In the summertime, the water temperature reaches up to 26C, so you can enjoy a wetsuit free open water swimming experience. The river flow is very low and therefore is not dangerous to swim up or downriver. There are several river dams and watermills along the way and these spots are usually the best to walk around.

Kupaliste Jurovo near the town of Metlika is one of the best swimming spots with the clearest water on the Kolpa river. Right there is also the confluence of Kolpa and Lahinja rivers which makes it even more adventurous to explore. There is no motorized-boat traffic around, you can swim freely by yourself.  You may see other people in kayaks, canoes or small boats paddling around. We operate a 4-day river swimming holiday on the Kolpa river in the summer.
