Geological Framework and Alpine-Hinterland Context

Passo dei Due Santi, nestled at 1,090 meters above sea level on the ancient border between Tuscany and Liguria, marks the transition from the lush valleys of Lunigiana to the rugged crags of the Apuan and Tuscan-Emilian Apennines. This saddle-shaped pass sits atop a series of ophiolitic outcrops—remnants of the ancient Ligurian ocean crust—now exposed through tectonic uplift and erosion. Peridotite and serpentinite boulders pockmark the slopes, creating a dramatic mosaic of green-hued rocks against a backdrop of chestnut and beech woodlands. Visitors searching for “Passo dei Due Santi hiking,” “Lunigiana trekking routes,” and “Appennino Tosco-Emiliano geology” will discover how these unique lithologies influence soil chemistry and local biodiversity.
