Tips for Lake Peirou to Glanum Ruins Walk

  • On the way back, there’s a short section through a tunnel which is very steep. There are metal staples and a chain to hold onto, but it’s not advised if you’re very afraid of heights or not at least slightly flexible.
  • Stay in Saint-Rémy-de-Provence* so you can walk to Glanum Ruins and Lake Peirou from your hotel.
  • For a longer walk, you can head up to the Rocher des Deux Trous from the ruins, or walk elsewhere in Provence such as in Buoux Gorge or around Les Baux de Provence.
  • Glanum ruins are open Apr-Sep 9:30am-6pm every day and Oct-Mar 10-5pm Tue-Sun.

From the car park head to the lake and follow the path around its left side. There are some lovely views from here across the little lakes to the cliffs above. About halfway along the water’s edge, take the path leading left, away from the lake, and directly upwards.

Follow the path as it climbs over the ridge and down the other side. There are nice views from here of Saint-Rémy-de-Provence town and the surrounding countryside.

Soon you’ll get to a track at the bottom. Turn left here to walk past some villas and you’ll come out at the parking to Glanum Archeological Site. Cross over the road and head right up the lane to the ruins if you want to visit these. Or to head back to the lake, continue walking along the main road.

Once you’re finished with the ruins, return to the main road and head left. You have to walk along the road for about 400 metres, before you’ll see a path leading to the right and into the trees.

This trail leads upwards and then to the base of a large, rocky cliff. The route now leads steeply down through a tunnel at the base of the cliff. There are metal staples for steps and a metal chain to hold on to while making the descent. It’s not too difficult, as long as you don’t have a fear of heights and are a bit flexible.

Guidebooks for Exploring & Hiking in Southern France

If you’re going to southern France, there are several guidebooks that cover either only Provence & Côte d’Azur (Avignon and east), or Languedoc-Roussillon (Nîmes/Montpellier and west). Because we explored both areas, we opted for Lonely Planet’s France Guide, which apart from including all of France was only slightly more expensive than an individual regional guide.
