The well-known seaside resort is located at the southern tip of Istria. The place has a splendidly structured, long coastline and is surrounded by a chain of small islands. Today Medulin is a well-known tourist center. To him belongs also the village Pješćana uvala, in German about "sandy bay", with the so-called "sandy beach", actually rather a grit and gravel beach. The towns of Pomer, Vinkuran, Premantura and Banjole belong to Medulin.

Medulin also includes the peninsula Vižula, which is known for its ancient archaeological site.
