In the morning, we depart to Blue Eye. The Blue Eye is a water spring and natural phenomenon. As we travel towards the Blue Eye via winding, steep, uphill roads, you will pass through different landscapes; from palm trees on the shore, to green and dense, almost mountainous forest areas. A narrow path will take you first to crystal clear River Bistrica; a breathtaking site, that is not far from your destination. Its most striking feature is the unrealistically blue emerald color that changes tonality and intensity before your eyes, depending on the intensity and angle of light falling on the springing water. The clear blue water of the river bubbles forth from a stunning, more than fifty-meter-deep pool and has a constant temperature of 10 degrees Celsius.
