Things to see


The countryside is home to outstanding natural values. The area has become protected, with unique sandstone and marl formations, such as the 80-meter-high Strunjan rock wall on the Adriatic coast. The pristine rocky ranges run for several kilometres on the Strunjan Peninsula, making the landscape special both geologically and in terms of fauna and flora.

The protected area is home to many plant species already threatened with extinction in other parts of Slovenia, and the fresh waters of the Strunjan stream delta are teeming with wildlife.

Salt pools

Today, only a few wetlands remain on the Slovenian coast. They were once abundant here but have evolved into salt basins. Today, only Strunjan and Secovlje have such wetlands in complete harmony with nature. The area was declared a nature reserve in 2001, and a museum has been set up to learn more about nationally significant salt production.

The salt marsh in Secovlje covers an area of ​​650 hectares and is the most ornithologically significant in the country. The composition of the birds that live, nest and overwinter here is much more varied than in similar areas. Of the 288 bird species found here, 90 also spend time here.
