About this spot

Kap Kosaca sits along Croatia's rugged coastline, accessible from the Luka Sveti Grgur area. The site welcomes divers throughout the year, making it a flexible choice for Adriatic exploration. With 12 recorded species observations, the location supports a working marine ecosystem worth investigating. Croatian diving in this region benefits from the country's well-established dive tourism infrastructure and boat access.
