Vikos–Aoös National Park, National park in Epirus, Greece

Vikos–Aoös National Park is a protected area in the mountains of Epirus that combines deep gorges, dense forests, and high peaks. It stretches across a large territory with varied plant and animal life, where multiple rivers wind through the landscape.

The park was established in 1973, one of ten national parks in mainland Greece, and named after the Vikos and Aoös gorges. The Vikos Gorge was carved by the Voidomatis river; its slopes expose Eocene limestone above Campanian strata, with Jurassic and Cretaceous limestone and grey Jurassic dolomite below. From the 17th to the 19th century, Zagori communities held autonomous status and grew wealthy through trade, becoming a centre of folk medicine.

Shepherds and their flocks have shaped this mountain landscape for generations and still use it for grazing today. The traditional stone villages throughout the region show how people adapted to live in this rugged terrain.

Visitors can hike along marked trails connecting traditional villages or use the river for water activities. It is advisable to bring proper gear and water, especially if you plan to explore longer routes.

The Guinness Book of Records lists the Vikos Gorge as the deepest canyon in the world in proportion to its width, citing a point where it is 900 m deep and 1,100 m wide from rim to rim. Some local guides dispute the claim. The gorge's walls expose Eocene limestone above Campanian strata, with Jurassic and Cretaceous limestone and grey Jurassic dolomite in the deepest layers.
