You would think this river is located in an isolated area but it runs through a small town that we happened to be driving through. We were waiting to drive across the bridge as there were quite a few people crossing the roads. I remember saying 'Why are there so many people here?' and, lo and behold, as soon as we crossed the bridge, we gasped simultaneously, looked at each other with the 'so that's why' look.
We parked across the street of the river, ordered a coffee in one of the small cafes lined up along the street, crossed the street and sat down on the rocks whilst watching people take photos and jumping around the rocks. Of course, we joined the crowd and did the exact same thing after finishing our coffee.
