Nadiža under the Napoleon Bridge (Robidišče)
In the far west of Slovenia, near Robidišče, the torrential Nadiža river has dug a beautiful pool more than 100 m long and up to about 5 m deep beneath an old stone 'Napoleon' bridge – not to be confused with the better-known one over the Soča at Kobarid, about 11 km east. At low summer flow the water warms to around 20 °C and the current is weak, making it an easy, shallow dive. You swim upstream under the bridge to the head of the pool and return the same way, roughly 30 minutes. Fish are smaller than in the Soča or Idrijca but wait in the deepest spots; the gravel bottom is mostly bare, with many leaves in autumn.
Tiefe: 0–5 m
