Amazing hike! Tough one but worth it. And more signs would be helpful, especially in foggy weather you can otherwise get lost easily.
WATCH OUT: The navigation is misleading though - at the first intersection, do not stick with the signs for the loop (left) but stay west (right) of the river. If you follow the recorded navigation, you will end up in a muddy swamp-like area in between both official trails. The way up to the mountain then has no signs but leaves it up to you to figure it out...
