My personal bugbear is that of clean water. We take it for granted that we can turn on a tap and have water so good we can drink it, let alone wash in it or clean our clothes in it. Sadly this isn’t the case in a lot of the world.
In Slovenia in the Vintgar Gorge flows some of the clearest water I have ever seen. The 1.6 km long Vintgar gorge carves its way through the vertical rocks of the Hom and Bort hills and is graced by the Radovna with its waterfalls, pools and rapids.
Discovered in 1891 by Jakob Žumer and Benedikt Lergetporer, the gorge was soon after equipped with wooden observation walkways and bridges, and was opened to the public on August 26, 1893. Wikipedia
On a hot day there is nothing better than walking through this gorge in the shade with the sound of the water beside you.
