At around 1100m we reach a col which turned left towards the Revuaire or right to the Pas de Jubeo and back towards our initial plan, which is the way we went. Descending briefly but steeply we soon reach another col, with great views northwards outside of the bowl of rock, then head south ourselves back into the bowl.
But the real treat was the view from the Montagne de St-Genis and the ridge that runs east to west back towards the end of the walk. The views were just magnificent and hard to do justice to in either words or photos. With the soft, hazy afternoon light just bright enough to allow a clear view of the distant peaks of the Maritime Alps and even a hint of the Ecrins National Park as well, alongside the rolling and still lofty hills and peaks of Provence all connected by the flat and fertile Durance valley, it was amazing.
Walking the ridge in late afternoon, picking our way along the steeply sloping path with sheer drops on our left and a steep slope away to the south we made slow progress, partly because of the terrain but also because of the urge to take photos every few hundred metres (including of the numerous fossils and even a herd of Chamois far below that we spotted along the way).
When we finally reached the end of the ridge and began our descent back to the Plan d'eau du Riou it was in fading evening light and by the time we reached Homer it was near dark, after an 8 hour hike in excess of 25km. But, as an extra bonus, spending the night by the tranquil reservoir was the ideal way to recover with just the sound of ducks the following morning to disturb us, just in time to catch an amazing sunrise over the water.
