Bormide.
Truffles grow in the valleys along the forks of the Bormida river. Millesimo, capital of the precious tubers dedicates a national festival to them each year.

Within the Langhe di Piana Crixia protected area you can admire a marvelous stone mushroom: the rock weighs 2,600 quintals (57,300 lbs), it is 14 meters (46 ft) high, and the perfectly balanced shape above its slender base is stunning. It is one of the gullies-sedimentary rock formations sculpted by wind and water.

A short distance away, fascinating karstic shapes characterize the surface and depths of the Bric Tana regional park, where limestone spires tower over the dense forests creating a striking natural scene. Discoveries found here, at Tana dell'Orpe, bear witness to the presence of humankind since prehistory. More recently, there was Napoleon's passage at Cairo Montenotte, where in 1796 he defeated the Austrians. Various examples of military architecture survive from the period, and can be visited on outing into the greenery among the caves, dolines, and ancient menhirs.
