Sooo worth a visit. Excellent hiking, especially on foot from Kemer, blue water, almost no one in early spring. Admission is about 150 coins per person
I liked it, it was very atmospheric. We were in January, there were almost no visitors. We didn't reach the end of the trail, the stream blocked the way, and we didn't want to wet our shoes. The entrance is paid, I don't remember the price, it's not expensive.
