A lovely little quiet place with a Vival and one of my favorite campsites. Everything is top-notch, and the owners are incredibly friendly. A spectacular area for cycling and hiking. A completely underrated region with hardly any traffic.

On this section you will at times have the feeling of going off-road. The foothills of the Devoluy massif that cover the bottom of the landscape help to make this passage exotic. You can admire the Rattier or the Bonnet de l'Évêque, which peak at 2,474 and 2,663 meters respectively. These steep peaks hide behind them the roof of the Devoluy: the Obiou.

From this superb gravel path, which winds through pastures, you can admire the first summits of the Devoluy massif. Its summit, the Grande Tête de l'Obiou, culminates at 2,789 meters.

Very nice place, more like a parkland than a campsite. Lots of small and large rental tents and huts, everything very nice and lovely. Lally is a small, creative place.
