Beautiful bike ride right along the lake. Make sure to stop in Saint-Julien-du Verdon and enjoy a cool drink down by the lake. There is also a small snack bar if you get a little hungry.

Beautiful landscape, small road, only the last bends are strenuous.

The Col des Robines peaks at 988m and will allow you to climb to almost 1000m without making any effort because from Moriez you would have a slope of around 3km with a slope not exceeding 5% and on the Saint-André les Alpes side this will be shorter, around 1.5 km, but harder with an average of 6-7%. Be careful, however, of the often very heavy traffic on this pass because it is on the RN 202 which is HUGELY used almost all year round.

At the bend of a hairpin bend, this egg is a work of Andy Goldsworthy. This is one of the three “Sentinels” of the Refuge d’Art course; it represents the Asse valley.

Lake Castillon results from a water reservoir at the Cheiron hill. When the dam was installed, water engulfed the village of Castillon and the Saint-Julien bridge. This lake with azure waters is perfect for cooling off.

On the western slope, after going up the long Asse de Clumanc Valley from Barrême, the difficulties really begin in Tartonne with a first ramp of 1.5 km at 6.5%. Then after a small flat area comes a nice final of 2.6 km where the slope will be around 7%. On this side you can see one of Andy Goldsworthy's sentinels, an ovoid-shaped cairn placed at the side of the road as part of an artistic trail created by this renowned artist practicing land art. On the eastern slope, nothing very complicated until Lambruisse with 5 km where the hardest passage will not exceed 4.5%. On the other hand, things become tougher with the final including 1.8 km at 6.5% on average, but the last 350 meters are at 8.5%. The road is very beautiful and quiet on both sides. This pass is enchanting.

This strange construction which sits in one of the bends of the Col du Défens is in reality a work by Andy Goldsworthy, a major figure in land art. It is part of the route entitled “Refuge d’art” which offers a 150 kilometer hike, imagined and created by the British artist through the National Geological Nature Reserve of Haute-Provence. This artistic itinerary, original and unique in Europe, combining contemporary art, hiking and rural heritage, includes ten works scattered throughout the Dignois region. Among them, three ovoid stone cairns, designated as “Sentinels”, one for each of the three valleys of the Haute-Provence Geological Reserve. Besides this one which represents the Asse valley, you can find another sentinel in the Clue de Barles, at the edge of the road at the foot of the cliff, representing the Bès valley, and the third in the commune of Authon in the Vançon valley. “It is the top of the cairn which brings the energy of the stone to its peak, just as it is in the keystone of an arch that all the energy is concentrated. »Andy Goldsworthy Andy Goldsworthy's work and vision were the subject of a film entitled "Rivers and tides" which you can see here: https://www.dailymotion.com/video/x15e83f?playlist=x54l1y or just the trailer: https://www.dailymotion.com/video/xjggqk?fbclid=IwAR2l_oUGJuU5sc5vLobLojCfRrBf3xa42fqjOKc-uL4DrOQomGKoypSHfWk For more information on the “Refuge d’art” route: https://www.tourisme-alpes-haute-provence.com/refuge-art-andy-goldsworthy/

The ascent of the Col du Défens is on a good quality road with very little traffic, beautiful scenery and an easy climb on both sides. The icing on the cake is an egg-shaped sculpture by Andy Goldworthy that you will come across at some point.
