The sun never goes away!
So best way to avoid any tourists it to show up at midnight in the summer. It was a little chilli but what a view.
The first rivers was easy to cross as there was little water. The second one was complicated to cross with 2 DSLR, and tripods. Being narrow this made the current strong. I did scare myself a couple time as it was hard to evaluate the depth of the very clear water.
It was well worth the efforts.
