Classic loop trail that connects the Sette Selle mountain hut to the picturesque Lake Erdemolo.

The trail, with various ups and downs, leads along the high route—skirting rather than climbing the surrounding peaks—to Lake Erdemolo. The return is via trail 324, which, with more elevation changes at a lower altitude, intersects with the junction for trail 343B and then climbs back up to the hut.
