Hiking in Drôme Provençale doesn’t make it onto the big lists. It’s not a trendy destination, not a name people immediately recognise. The region draws no attention and doesn’t ask for any. But once you’re out there, walking through rugged valleys with thyme underfoot and limestone cliffs rising above you, you understand why hikers come back here time and time again. This corner of southern France carries the promise of Provence within it, but feels rougher, quieter and more genuine.
I hiked six trails in Drôme Provençale, based in Saou for the week. And those were six days of pure enjoyment: the views, the trails, and everything in between.
Where is Drôme Provençale?
The Drôme département lies southeast of Lyon, on the eastern side of the Rhône valley. It’s a region of contrasts: to the northeast, the rugged limestone plateaus of the Vercors massif; to the south, the Mediterranean heart of Drôme Provençale with lavender fields, olive groves and cypress trees on the horizon.
The area around Saou, Crest and Le Poët-Laval sits in the middle of that transition. You’re not yet in the flat, sun-drenched Provence, but you’ve already left the cooler mountain world of the north behind. The landscape becomes more varied the deeper you walk into the valleys: forested ridges, narrow gorges, open meadows and then sudden limestone walls that make you feel like you’ve gone somewhere far away.
How These Mountains Were Formed
To understand the landscape, it helps to go back in time. Around 150 million years ago, during the Jurassic period, a shallow sea covered this area — part of the ancient Tethys Ocean. On the seabed, layers of limestone and marl slowly accumulated, formed from animal matter and sediment. Layer upon layer, over millions of years.
When the Alps rose, roughly 30 to 40 million years ago, those solidified seafloor layers were pushed upward, folded and fractured. The limestone broke and tilted. What now stands as a mountain ridge was once lying flat on the bottom of a sea. That’s why, in many places across Drôme Provençale, you can see layered limestone walls standing almost vertical — like open books.
The finest example of this stands right in front of you when you’re in Saou: the Forêt de Saou. This is what geologists call a synclinal perché — an uplifted syncline where the rock layers have been bent upward rather than downward. A basin of limestone and forested hills, sealed in by an impressive wall of cliffs. Above that wall rise the Trois Becs: three limestone peaks, the highest reaching 1,589 metres. You can see them from almost everywhere in the region.
Wind and water did the rest: streams carved gorges into the soft rock, rain dissolved limestone and formed caves and sinkholes. The landscape you walk through today is the result of an interplay between sea, mountain-building and erosion across a timescale that exceeds human comprehension.
The Landscape as a Hiker
You feel that geology underfoot with every step. If you walk on limestone gravel that crunches beneath your soles. You climb past rocky outcrops and descend into valleys where a stream flows over a bed of white pebbles.
The vegetation tells the same story. On the sunny slopes grow lavender, thyme, broom and holm oak — Mediterranean plants adapted to the dry, calcium-rich soil. The moment you reach the shaded side of a ridge, that changes abruptly to beech forest. That constant alternation is what makes hiking here so satisfying.
The wildlife fits too. If you’re lucky, you might spot chamois on the limestone cliffs, griffon vultures riding the thermals above the rock faces, golden eagles high in the sky. And in spring: orchids on the open meadows, more species than you’d expect.
The Villages of Drôme Provençale
Most villages in Drôme Provençale sit high up. Not by accident. During the Middle Ages, between the eleventh and fourteenth centuries, the people of this region were constantly threatened by raids, looting and religious conflict. A village on a rock was a village that could defend itself. These are called villages perchés: hushed medieval settlements perched on rocky outcrops, with views over the valleys below.
Saou sits at the foot of the Forêt de Saou, in the shadow of the Trois Becs. It’s a lively, artistic village with studios, an organic grocer and café terraces under the plane trees. Most of the hikes in this area start directly from Saou into the forest, heading towards the limestone ridges that encircle the village. It makes an ideal base.
Bourdeaux is quieter in character. Driving in, you can already see the ruins of two castles from the twelfth and thirteenth centuries rising above the village. From the top, there’s a wide view over the surrounding landscape and the three points of the Trois Becs on the horizon.
Le Poët-Laval is one of France’s officially most beautiful villages, listed among the Plus Beaux Villages de France. The word poët means ‘small peak’ in the local dialect, Laval meaning the valley. In the thirteenth century, the Knights of Malta built a castle here; the remains still stand. Narrow lanes, stone steps, old houses and a Protestant church now serving as a museum all recall the religious wars that hit this village hard. The same Huguenot Trail that passes through Le Poët-Laval runs all the way to Geneva — 1,600 kilometres along the escape routes of the Huguenots after the revocation of the Edict of Nantes in 1598.
Crest is the only real town in the area, situated on the river Drôme. It’s dominated by the Tour de Crest, the tallest medieval tower in France, rising above the terracotta rooftops like a quiet sentinel.
Six Hikes Around Saou and the Surrounding Area
1. Grand et Petit Pomerolle
This is the most demanding and most rewarding hike of the week. The route climbs from the Forêt de Saou through beech forest to the limestone ridges, first to the Petit Pomerolle and then, for those who press on, to the Grand Pomerolle. Along the narrow ridge paths, you have views over the valleys on both sides. The descent follows the Pas de Jossaud, a distinctive notch in the mountain ridge. At one point the descent becomes very steep — on this hike it really helps to be sure-footed and confident on rocky terrain.
The route calls for sturdy hiking boots and a good fitness level, particularly for the steeper, rocky sections on the way down. The full loop takes just under six hours. Those who prefer to cut it short can turn back after the Petit Pomerolle, or reverse the route and return the same way from the Grand Pomerolle. Alternatively, walk the route in reverse and return the same way after the Grand Pomerolle.
Distance: 13 km. Elevation gain: 720 m. Duration: approximately 5h45 (full loop).
2. Roche Colombe
The Roche Colombe is the striking rocky summit that rises above Saou and can be spotted from far away. The loop trail starts in the village and climbs steadily through the Forêt de Saou, alternating between woodland and open limestone slopes. At the top, a panorama opens over the whole area: the valleys, the Trois Becs and, on clear days, far to the south.
A solid hike, but shorter than the Pomerolle route. Works well combined with a quiet afternoon in Saou itself.
Distance: 10 km. Elevation gain: 650 m. Duration: approximately 4h30.
3. Around the Lower Slopes of Saou
For a day when the legs need a rest from serious climbing, the short loop around the lower slopes of Saou is a fine choice. Little elevation gain, but plenty of atmosphere. You walk through the lower part of the Forêt de Saou, past Mediterranean oaks and along paths with views up to the cliffs above. A walk for taking a breath and absorbing the surroundings at a slower pace.
Distance: 5.5 km. Elevation gain: 140 m. Duration: approximately 2 hours.
4. Walking from Bourdeaux
Bourdeaux itself is worth visiting for the castle ruins and the views over the surrounding landscape. The walk heads into the area behind the village: out and back, not a loop, but that gives you the freedom to decide how far you go and when to turn around.
The landscape around Bourdeaux is softer than around Saou, with more open meadows and scattered farmhouses in the hills. A walk for those who want to enjoy the countryside without every step feeling like a mission.
5. Walking from Crest
Crest has more to offer than the Tour de Crest alone. The walk that starts from the town heads into the area behind it: first through meadows, then upward into the forest, along paths that take you well away from daily life. Halfway along, we found a spot beside the path to sit and have lunch. No terrace, no menu, no rush: just the surroundings, the sound of the wind and the feeling of being exactly where you should be.
Higher up in the forest, the view shifts from what you’d expect looking up from the town. The Tour de Crest, which loomed so large from below, becomes a small dot in the landscape.
6. Le Poët-Laval
Le Poët-Laval sits in this list more as a day trip than as a hike, but it earns its place. The village is too beautiful to skip. Narrow lanes, stone steps, gardens spilling over the walls. We wandered through the streets, took in the remains of the Knights of Malta castle and eventually sat down on a sun-drenched terrace. That terrace was the best part of the day.
Combine Le Poët-Laval with a walk in the surrounding hills: the village itself can be explored in an hour, but the ridges around it invite you to keep going.
Practical Information
Getting There
The nearest major station is Montélimar, on the TGV line between Lyon and Marseille. From Montélimar, a hire car takes about thirty minutes to Crest, and another fifteen to Saou. From the UK, the journey by train via Paris or Brussels takes roughly six to seven hours to Montélimar.
By car: the A7 motorway along the Rhône brings you to the Montélimar Sud or Loriol-sur-Drôme exit. From there, take the departmental roads towards Crest and Saou.
When to Go
Spring and autumn are the best seasons for hiking in Drôme Provençale. In April and May the landscape is in bloom, the trails are quiet and the temperature is comfortable, between 15 and 22 degrees Celsius. September and October bring beautiful autumn colours and a softer light.
Summer is warm, sometimes very warm: on the exposed limestone paths the sun can be relentless. Starting early and finishing before midday is the sensible approach. In winter, the higher routes can be impassable due to snow on the limestone ridges.
How Long to Stay
A week is ideal for six hikes in this area. It gives you time to walk every day, rest in the afternoon and explore the villages in the evening. Saou is an excellent base: everything is within easy driving distance and the village itself has enough character to make every evening enjoyable.
Where to Stay
The area has a good range of chambres d’hôtes, small hotels and campsites. Saou has several characterful options right at the edge of the Forêt de Saou. In Le Poët-Laval, you sleep in the heart of one of the most beautiful villages in the region. Dieulefit, a little further south, is a livelier base with more amenities.
On every trip I bring my own reusable water bottle #ad. My aim is to cut out single-use plastic, and refilling instead of discarding is one of the easiest ways to contribute as a traveller. A foldable bag for small purchases also cuts down on unnecessary plastic waste along the way.
