Slavyanka (mountain) in the context of "Pirin Mountain"

Golyam Perelik (Bulgarian: Голям Перелик [ɡoˈʎam pɛrɛˈlik]) is the highest peak in the Rhodope Mountains, situated 19 km to the west of Smolyan. It makes the Rhodopes the seventh highest Bulgarian mountain range after Rila, Pirin, Stara Planina, Vitosha, Osogovo and Slavyanka. The peak is easily accessible, but currently cannot be climbed because a unit of the Bulgarian Army is stationed in its vicinity.

Perelik Point on Robert Island, South Shetland Islands is named after Golyam Perelik.

The Pirinska Bistritsa or Mpístritsas (Bulgarian: Пиринска Бистрица, Greek: Μπίστριτσας) is a river in south-western Bulgaria and northern Greece, a left tributary of the Struma. The river is 53 km long; the last 7 km before its confluence with the Struma forms the border between Bulgaria and Greece. Pirinska Bistritsa drains the south-western sections of the Pirin mountain range and the northern sections of the Slavyanka mountain range.

The river springs from the southern shore of the Argirovo glacial lake in situated in the Demirkapia cirque in Northern Pirin at an altitude of 2,365 m. It flows in southern direction in a deep valley. Near Pirin refuge it turns to the southeast and enters a densely forested area, where it again flows southwards. At the village of Pirin the river takes a sharp turn to the southwest and enters a sparsely forested valley with eroded slopes. At the village of Katuntsi it enters the Sandanski–Petrich Valley, where the river bed widens. At half a kilometer south of the village of Novo Hodzhovo is the confluence with the river Petrovska reka. From that point it forms the border between Bulgaria and Greece until its confluence with the Struma at an altitude of 69 m between the villages of Kulata and Promachonas.

Paril (Bulgarian: Парил) is a mountain saddle (pass) in western Bulgaria between the mountain ranges of Pirin to the north and Slavyanka to the south. It is situated on the territory of the Sandanski and Hadzhidimovo municipalities in Blagoevgrad Province.

The pass is 10.6 km long with a maximum altitude of 1176 m. It connects the Sandanski-Petrich Valley of the river Struma basin in the west and the Gotse Delchev Valley of the river Mesta basin in the east.

Ali Botush (Bulgarian: Али ботуш), also spelled Alibotoush, is a nature reserve in the small mountain range of Slavyanka, located on the border between Bulgaria and Greece. The reserve occupies the northern section of the mountain which lies within the territory of Bulgaria and takes its name from the old name of Slavyanka. It is situated in the municipalities of Sandanski and Hadzhidimovo, Blagoevgrad Province. It was declared in 1951 to protect the largest forests of the endemic Bosnian pine (Pinus heldreichii) in the Balkan Peninsula. Its territory was further expanded several times and spans an area of 1638 ha or 16,38 km. It was declared a UNESCO Biosphere Reserve in 1977.

The reserve was created to protect the largest forests of Bosnian pine (Pinus heldreichii) in the Balkans and is renowned for its rich flora — over 1500 species found within its limited territory.
