I've been swimming my whole life. I've coached athletes from beginners to elite level. But there is something about swimming in open water — specifically the Adriatic — that no pool in the world can replicate. The colour of it. The temperature. The way the light moves through it in the morning, when the boat is at anchor and you're the only person in the water and the world hasn't woken up yet.

That feeling is what Swim Traveller was built around. And our 2025 Croatia cruise — eight days sailing north from Dubrovnik to Split aboard a private yacht, swimming every day, stopping at some of the Dalmatian coast's most beautiful islands — was exactly that. It's the reason we believe Croatia small ship cruises are the finest way to experience this coastline.

This is a recap of what we did, what made it extraordinary, and why 2027 is going to be even better.

Who We Are: Croatia Cruise Specialists by Fluid Movement

Lorna holds multiple certifications in swim theory and technique. She coaches everyone from nervous first-timers to seasoned open water competitors. Between swims, we step ashore — exploring ancient cities, visiting tucked-away wine cellars, and immersing ourselves in the culture that shapes the coastline. These moments are not add-ons. They are part of the rhythm of the journey.

Why Croatia Small Ship Cruises Are the Best Way to Swim the Adriatic

The Dalmatian coast is one of the finest open water swimming environments on earth — and Croatia small ship cruises are the only way to access most of it. The Adriatic is calm, warm from June through September, and extraordinarily clear thanks to the geology of the karst coastline. On the best days, visibility stretches beyond fifteen metres. Large commercial cruise ships simply cannot reach the coves, saltwater lakes, and sheltered passages that define the best of this coastline.

The clarity comes down to geology. The Croatian National Tourist Board notes that the Adriatic's karst limestone coastline filters rainwater before it ever reaches the sea, which is a large part of why visibility here rivals almost anywhere else in the Mediterranean.

The 2025 Route: Dubrovnik to Split — Croatia Small Ship Cruises

Highlights from the 2025 Croatia cruise route:

• Mljet National Park — swimming in the famous lakes, which are even warmer than the ocean & surrounded by beautiful forest trials. Evolution of these lakes has transformed them into a unique blend of both fresh & salt water & home to both types of marine life, which makes swimming in them so special. The Mljet National Park authority has more on the park's history and conservation work if you'd like to read ahead of your visit.
• Korčula — the walled medieval town rising straight from the water, with one of the finest old-town harbours on the coast
• Zlatni Rat, Bol — one of Croatia's most iconic beaches, reached by swim from the yacht, with a wine tour en route through Pučišća
• The secret stop — one anchorage kept off the itinerary each year. Past guests say it's the highlight of the trip.

The Swimming: Guided, Coached, and Entirely at Your Level

Every swim on our Croatia yacht cruise is guided, monitored, and structured — but never pressured. Daily swims range from 1km to 4km. You can push for distance, or simply float in a sheltered bay. Both are valid. Both are the point. Our safety approach follows the guidance set out by World Aquatics for open water events, adapted for a relaxed group setting rather than a race.

Lorna leads every swim personally, with safety boats and kayak guides throughout. Every swim is briefed in advance and debriefed after — technique observations, breathing drills, open water sighting. Guests who came as recreational swimmers have left as confident open water athletes.

The Yacht: What Sets Our Croatia Small Ship Cruises Apart

A privately chartered 35-metre catamaran — spacious enough to breathe, small enough to go places standard Croatia cruises never reach. With 15 en-suite cabins and a maximum of 28 guests, there is always space to find your own corner of the deck. The jacuzzi on the upper deck became a post-swim ritual. Three and four-course lunches daily from a gifted onboard chef.

The yacht carries kayaks, SUP boards and snorkelling equipment. Free Wi-Fi, daily cabin service, all harbour fees included. But the defining advantage of Croatia small ship cruises is access: we anchor in coves, saltwater lakes, and sheltered passages that larger vessels simply cannot reach. The secret stop. The forest-framed bay. The water in those places is different.

Evenings Ashore: Culture, Wine, and the Dalmatian Table

On the 2025 trip, evenings ashore included a private visit to Stina Winery in Bol, a walk through the Roman streets of Diocletian's Palace in Split at dusk, and long lunches at harbourside restaurants that the locals actually use. The palace complex is a UNESCO World Heritage Site, and walking it after the day-trippers have left is one of the quieter pleasures of the week.

Who Joins a Swim Traveller Croatia Cruise

The 2025 group included an 80-year-old venturing on her first international swim trip. A masters swimmer who's circled the globe many times on various open water swim adventures. Pool enthusiasts and their friends who — after dedicated practice — had ambitions to take their skills to the ocean. Several solo travellers who arrived not knowing anyone and left with new friends across the world and a group chat that's still active.

Twenty-eight people is not a tour group. It's a community. Croatia small ship cruises attract a particular kind of traveller — curious, active, open to the unexpected. The Adriatic is very good at building them into something more.
