The little road that goes down from Cholonge is great and on arrival you have a superb view of Lake Lafrey

I did it on gravel, climbing via the Aveillans hill (west), it was fine. Direct descent to Putteville, very limited at the beginning on gravel, much steeper but it was fine.

1st part very smooth and very pleasant, 2nd part much more technical with a nice climb on a very greasy muddy path, steep slopes and quite technical descents. The final does not take the greenway recently set up and which allows you to avoid the road.

Take the time to stop and enjoy the scenery. This view of the Pierre-Châtel lake is quite rare. From here you have a perfect vantage point to see the alignment of the three lakes.
