What to do in Ardèche in August? Our ideas
1. Enjoy swimming and water activities
In August, water reigns. Swimming in the river, in natural pools or in the pool: it is the best way to enjoy the heat. For canoeing under the Pont d’Arc, set off early in the morning to avoid the crowds and the heat.
2. Experience the night markets and village atmosphere
Every evening, the villages come alive with night markets and summer festivities: music, crafts, local produce and good cheer in the mild night air. It is the very essence of summer. Check the days and locations with the tourist offices, as they vary.
3. Watch the starry sky
August nights, mild and often clear, are ideal for looking up. The region enjoys a sky with little light pollution. It is also the period of the shooting stars (the Perseids), generally around mid-August: a magical spectacle to watch lying in the park.
4. Admire the lavender of the neighbouring Drôme Provençale
In August, the lavender is harvested in the Drôme Provençale and the Tricastin, across the Rhône (not in Ardèche itself). The fields then take on a darker shade before the cut, and the air is fragrant. A lovely, very close excursion, best done in the morning.
5. Organise your days against the heat
The secret of August: activities early in the morning (swimming, canoeing, visits), rest and pool during the hot hours, outings in the evening. The Chauvet 2 and Aven d’Orgnac caves, cool all year, are perfect in the middle of the afternoon. Also wander through Bourg-Saint-Andéol in the shade of the lanes.

Is August a good month to come to Ardèche?
Yes, if you love festive, lively summer. It is the ideal month for family holidays, swimming and evenings, provided you accept the heat and the heavy crowds. With good organisation and a pool to cool off, August is unforgettable. Booking is essential, far in advance, including for a group stay.
Who is August ideal for (and less ideal)?
Ideal for: families on holiday, swimming fans, those who love the festive atmosphere, the night markets and the starry nights. Less ideal for: those who avoid heat and crowds, who will prefer June or September, more temperate and quiet.
