We arrived in the morning where the cold mountain water made a mist over the river. The trees were beautiful and green and the air was sweet.
After 700m or so, the gorge opens up and the path follows a dirt track along the river. A tall railway bridge comes into frame and the small Sum Waterfall. The trail lies a couple of kilometers outside the mountain lake town of Bled, and there are other beautiful mountain river walks in the vicinity.
