With a wide slope, from the sea to the 2200 meters of Saccarello Mountain, from which the stream giving it the name arises, the territory of Valle Argentina extends from Taggia to Triora.
However, the length of the valley is limited – it is about thirty kilometers along which the landscape turns from a purely coastal environment into a mountainous area, in the heart of the Park of Ligurian Alps, where it is not unusual spotting groundhogs, chamois and eagles. Saccarello Mountain, the highest peak of the whole region, from which it is possible to see Corsica, Albenga plain and Mercantour, is an authentic crossroad between Valle Argentina, Roya Valley (Provence) and Tanaro Valley (Piedmont), thus creating a mix of cultures and traditions. Among the dialects spoken in Alta Valle, it is not surprising to find Occitan.
The Valley includes BADALUCCO, TRIORA, REALDO, ANDAGNA, MONTALTO, MOLINI DI TRIORA, VERDEGGIA, POMPEIANA, TERZORIO and CREPPO.
