The economy of the village, a mainly agricultural one during the 19th and early 20th centuries (silkworms, fruit, wine, plus wood floating or charcoal transport on the river, and angling) occurred to change at the second half of the 20th century with the transformations on nearby Rhône Valley (canal on the Rhône, atomic industries in Marcoule by Bagnols-sur-Cèze and Eurodif in Pierrelatte, highway A7 from Lyon to Spain or French Riviera, TGV railways) : both arms of local economy are nowadays wine - the southern Côtes du Rhône - and tourism. Kayak and camping trips down the gorge are common in the summer. Saint-Martin-d'Ardèche, at crossroads of four "département"s - Ardèche, Gard, Drôme, Vaucluse - with its river beaches, canoe trips, hike and ride possibilities on hills around, plus historical townlets nearby and surrounding villages (megalithic sites with dolmens, visited caves, mediaeval chapels, Renaissance buildings), has become a touristic centre at the gateway of Provence.
