Albarine river running through the valley, a few kilometers under Charabotte waterfall.
Albarine river runs through Ain department and just after Hauteville Lompnès jumps a cliff of more than 100 meters. It's Charabotte waterfall which is the highest in the department.
I went there two days ago for a first visit of the waterfall and the lower valley. All the images were posted yesterday on my website, you can have a look here.
