The Karaburun Peninsula (Albanian: Gadishulli i Karaburunit) is a peninsula of the Mediterranean Sea located in Southern and Southeastern Europe, which is almost completely surrounded by both the Adriatic Sea to the north and the Ionian Sea to the south. It is located in Southwestern Albania along the Albanian Ionian Sea Coast, whereas the Strait of Otranto separates it from Italy. The Strait of Mezokanal separates the peninsula from Sazan Island, while in the southeast stretches the Bay of Vlorë. Its name “Karaburun” derives from Turkish for "black cape". In classical antiquity, its name was the "Akrokeraunian Peninsula" (Ακροκεραύνιο ακρωτήριο), whose name was derived from the eponymous Akrokeraunian mountains;this is because in terms of geology, the Rrëza e Kanalit on the peninsula represent the continuation of said mountains, which are the highest and most extensive mountain range system that extends parallel to the Ionian Sea.[1] Karaburun peninsula is sometimes called Ceraunian Peninsula due to the name of the mountain range.[2][3] Created during the mesozoic era of the cretaceous and paleogene period, the crests of the mountain range form a northwest-southeast line with a series of distinct peaks along its irregular structure that are broken apart by steep and unequally slopes.[4] The highest peaks are namely, the Maja Çaderës, Maja e Flamurit, Maja e Koretës and Maja e Ilqes.

Sazan (definite Albanian form: Sazani) is an uninhabited island inside the Mediterranean Sea in southern Albania. It is the largest island in Albania and strategically located between the Strait of Otranto and the entrance to the Bay of Vlorë, forming the border between the Adriatic and Ionian Sea. The island has a surface area of 5.7 km2 (2.2 sq mi) with a length of 4.8 km (3.0 mi), width of 2 km (1.2 mi) and a coastline of about 15 km (9.3 mi).

The island was open to the public in July 2015. 2,721.87 hectares (6,725.9 acres) of the territory of the island's surrounding marine area became part of the Karaburun-Sazan Marine Park in 2010.

Sazan is the largest island in the country and Albania's westernmost point. It is strategically located at the entrance to the Bay of Vlorë, in the eastern Strait of Otranto separating Italy from Albania. It is also located at the informal junction line of the Adriatic and Ionian Sea inside the Mediterranean Sea, which is just to the south according to international scientific bodies.
