Lacoste is a tiny, luminous hilltop village overlooking a valley of vineyards and cherry orchards. It occupies the same ridge as Bonnieux, visible across the valley, and shares the same honey-coloured limestone that characterises the Luberon villages. The dominant feature is the ruined Château de Lacoste on the skyline above — partially restored by its current owner Pierre Cardin, with an outdoor theatre carved from the hillside.
The village itself is small enough to see in an hour, but the views from the castle ruins — accessible on foot from the village — over the Luberon valley to the south and the Vaucluse plateau to the north are among the finest in the region.
