Small bridge, unfortunately unpaved cycle path, but beautiful landscape, partial views of the Chartreuse.

Nice little pass on the busy D1006

Since there is lighting and only a short tunnel, it works quite well. Before that, the entrance or information about the grotto.

Unfortunately, the D1006 is heavily trafficked, but luckily mostly with a bike lane uphill. No major climbs, but it drags on.

This is a good starting point for discovering our forest.

Be careful if komoot tells you 27% slope... it's actually just 5% (no GPS in the tunnel, komoot imagines that we go through the summit...)
