Baia di Panzano is entered between Punta Sdobba and Duino (45°46′N 13°36′E) about 3. 5 miles NE. The shores of the bay are bordered by a bank with depths of less than 5 m over it, which on the W side extends more than 1 mile offshore. Canale Quarantia, 2 miles NW of Punta Sdobba, forms one of the outlets of Fiume Isonzo, and Fiume Timavo flows into the bay through Canale San Giovanni about half mile NW of Duino.
