The lake formed when a coastal cave collapsed, leaving a depression that filled with seawater.
The name 'Mrtvo more' translates to 'Dead Sea' because the water is exceptionally calm compared to the open sea.
The island of Lokrum, where the lake is situated, has been protected as a Special Reserve of Forest Vegetation since 1964.
The lake's water chemistry is kept in equilibrium by subterranean passages that link it directly to the Adriatic.
The island is famous for the peacocks that roam freely, often spotted near the lake's edge.
Mrtvo more, or the Dead Sea, is a small, landlocked saltwater lake located on the island of Lokrum near Dubrovnik. The lake is connected to the open sea through underground channels, maintaining a constant water level and salinity. Its shallow depth and sheltered position make the water significantly warmer than the surrounding Adriatic Sea. The pond is surrounded by jagged limestone rocks and Mediterranean pine vegetation. It is a designated nature reserve within the Lokrum Special Forest Vegetation Reserve. The area is populated by a large number of free-roaming peacocks introduced in the 19th century. Swimming is permitted in the lake, which is popular with families due to its calm, pool-like conditions. Visitors reach the island via a ferry service departing from the Old Town Port of Dubrovnik.
The elevated rock ledge overlooking the full circumference of the lake provides the best perspective.
Bring water shoes, as the surrounding rock formations are sharp and slippery.
Pack a snorkel mask to observe the small fish that enter the lake through the underground channels.
Bring your own supplies, as there are no shops or facilities immediately adjacent to the water.
Do not attempt to feed the peacocks, as they can be aggressive; do not rely on local restaurants for supplies, as they are located away from the swimming area.
Accessible only during the ferry operational season, which typically runs from spring through autumn; inaccessible during winter months.
No jumping from the highest cliffs due to shallow areas; keep the area clean as it is a protected nature reserve.
