In winter, the water level is high enough to allow you to travel further into the cave. If there are any problems with the water level being too high, it is only after the snow melts.
The Altinbesik Cave can be reached by car or, more beautifully, as a short hike from Ürünlü. The cave is home to the largest underground lake in Turkey. In summer and winter, you can take guided boat tours into the interior of the cave. In winter and spring, the water level is too high for this.
