Izvor Cetine, also known as the Cetina Spring, is a natural wonder located in the Dalmatian Hinterland in Croatia. It is a karst spring located at the foot of Dinara mountain and is one of the largest sources of fresh water in the Dalmatian region.

The spring is surrounded by beautiful untouched nature, with crystal clear water that is so pure it appears almost turquoise in color. The area is also home to a diverse array of plant and animal life, including a number of rare and endangered species.

The Cetina River, which flows from the spring, is a popular destination for kayaking, canoeing, and rafting, and the surrounding mountains offer a range of hiking and climbing opportunities. Visitors can also explore the nearby historic towns of Sinj and Trilj, which are known for their rich cultural heritage and traditional cuisine.

Overall, Izvor Cetine is a stunning natural wonder and a must-see destination for anyone visiting the Dalmatian region of Croatia.
