From Malaucène, we followed Av. de Petrarque, then the main road to Mont Ventoux (D974) about 900 m where we forked right (signposts) before Chapelle Notre-Dame du Groseau. We then walked past some abandoned warehouses and located a narrow path which ascended in the woods and soon crossed the D974 road again. We now headed east and climbed along a good trail to Chapelle de Piaud which was the highest point of our hike (about 690 m). We forked right (south), and descended a bit before crossing the D974 again.

We descended rapidly along a wide but rocky trail to Combe Obscure where we forked right (south). At a crossroads we took the right-hand path and climbed to a long, mostly forested ridge. We descended slowly, heading southwest. We crossed another local road (D19) and continued towards Lac du Paty (300 m). We passed the Chapelle du Paty a little before the lake. The ascent to Chapelle de Piaud and the long forested ridge marked the most interesting parts of the hike. 

The final descent to the lake was steep. We then crossed a parking area, still following the GR de Pays markings, climbed a bit before turning northeast where we met the angry dogs. We came to a crossroads near Font Mourèle, headed north while the  GR de Pays trail turned left. We continued along a narrow paved road to the N938 road, crossed it and followed yellow markings. The trail made a small detour passing some vineyards before merging with another paved road, and we climbed along it to Saint-Michel by the N938 road. To avoid the busy road, our itinerary forked left and we descended along a paved road about 1,2 km then turned 90° right (east) then up to Col de Ronin (371 m) where we finally had Malaucène in sight.

However, the direct pedestrian route (Chemin du Col de Ronin) was blocked due to construction, and we had to follow the busy N938 down to the town centre. All in all, we would recommend an out and back hike, having for example the Chapelle du Paty as a turning point.
