The Blue Lagoon is one of the most popular day-trip destinations from Split, attracting thousands of visitors every summer with its crystal-clear turquoise waters, peaceful surroundings, and excellent snorkeling conditions. Located between the small islands of Drvenik Veliki and Drvenik Mali, it's a place where many travelers experience the Adriatic at its very best.
Whether you're looking to swim in clear water, relax on a boat, or spend a few hours exploring the Croatian coastline, a Blue Lagoon boat tour is one of the easiest and most rewarding ways to escape the city.
In this guide, we'll explain what makes the Blue Lagoon special, what to expect during your visit, how to choose the right tour, and share a few local tips to help you make the most of your day.
Despite its famous name, the Blue Lagoon isn't a man-made lagoon or a single beach. It's a large, sheltered bay known for its incredibly clear turquoise water, created by the combination of a sandy seabed, shallow depth, and abundant sunlight.
The official name of the area is Krknjaši Bay, but most visitors know it simply as the Blue Lagoon.
On calm summer days, the sea is so transparent that you can easily see the seabed several meters below the surface, making it one of the best places near Split for swimming and snorkeling.
The Blue Lagoon is located around 15 nautical miles southwest of Split, between the islands of Drvenik Veliki and Drvenik Mali.
It can only be reached by boat, making it a popular stop on both shared and private boat tours departing from Split and Trogir.
Because of its sheltered location, the water is often calm and inviting throughout the boating season.
The Blue Lagoon offers a combination that's difficult to find elsewhere so close to Split.
Visitors come here for:
Crystal-clear turquoise water
Excellent snorkeling
Calm swimming conditions
Beautiful island scenery
Easy access from Split
Relaxed atmosphere away from the city
Unlike crowded beaches, arriving by boat allows you to enjoy the Adriatic from a completely different perspective.
Most visitors spend between one and two hours at the Blue Lagoon.
During that time, you can:
Swim in crystal-clear water
Snorkel around the rocky shoreline
Relax on the boat
Sunbathe
Float in the calm bay
Take photos of the stunning scenery
“The experience is all about slowing down and enjoying the surroundings rather than rushing from one attraction to another.”
Absolutely.
The clear visibility and calm conditions make the Blue Lagoon one of the best snorkeling spots near Split.
While you won't find tropical coral reefs, you'll often see:
Small schools of fish
Sea urchins
Starfish
Rocky underwater formations
Posidonia seagrass meadows, which are an important part of the Adriatic ecosystem
If snorkeling equipment is included in your tour, it's well worth bringing a mask and spending some time exploring beneath the surface.
The Blue Lagoon is beautiful throughout the boating season, but each part of the year offers a slightly different experience.
May & June
Pleasant temperatures, fewer crowds, and exceptionally clear water.
July & August
Warmest sea temperatures and vibrant atmosphere, though also the busiest months.
September
A favorite among many locals. The sea remains warm, while the crowds begin to thin.
October
A quieter experience with mild weather, depending on sea conditions.
The Blue Lagoon is most commonly visited as part of a half-day boat tour, making it an excellent option for travelers who want to enjoy the Adriatic without dedicating an entire day.
However, it can also be included in a private full-day itinerary, allowing you to combine it with destinations such as Šolta, Trogir, Čiovo, or hidden bays that larger group tours often skip.
