It is a cryptodepression—a lake whose surface is above sea level, while its bottom is below sea level. This unique feature, combined with its location in the lower reaches of the Krka, makes it a valuable and protected part of the natural landscape.

The lake is connected to the sea by a narrow channel, which results in saltwater in its lower layers and freshwater at the surface. This mixing of river and marine influences creates specific natural conditions and a rich ecosystem. In the northern part of the lake lies the small island of Stipanac, while upstream along the Krka River, you can continue toward Krka National Park.

Lake Prokljan is surrounded by quiet settlements, greenery, and numerous coves perfect for relaxing, walking, and enjoying nature. Its indented coastline offers many opportunities for exploration, and the lake is particularly appealing to boating enthusiasts and those who prefer a slower, more contemplative experience of the landscape.

A visit to Lake Prokljan is an opportunity to experience a unique natural phenomenon, enjoy the silence, and discover a place where the river, sea, and land meet in a special way.
