Güzelcehisar Lav Sütunları
Located 17 km from Bartın city center, Güzelcehisar Lava Columns are a natural monument formed approximately 80 million years ago as a result of volcanic eruptions. These columns, which formed in pentagonal, hexagonal, and sometimes quadrilateral shapes due to the slow cooling of lava, were declared a Natural Monument in 2017. Similar formations exist in Northern Ireland, Scotland, and California, but in Turkey, they can only be seen in Bartın. The columns vary in diameter from 50-100 cm and can exceed 30 meters in height. Wooden walking paths and viewing terraces are available for visitors.
