Half the way through, you realize that even if nature is especially harsh here, tourism has left its lasting traces. At one of the few points where the pebbles along the river gives enough space, a handful of houses has been put up.
Here you will find restaurants and even a hotel. A great place to pass a night, and definitely different from most hotel experiences.
This would easily allow you the chance of making a walk through the gorge at the middle of the night. Quite scary and fascinating, I guess.
