Vikos Gorge is located in the Pindus Mountains in northern Greece and is considered one of the world's deepest gorges. It is part of the Vikos–Aoös National Park, which was established in 1973 and covers an area of 12,600 hectares. The gorge is approximately 20 kilometers long, with a depth that reaches up to 900 meters and a width that ranges from 400 meters to just a few meters.

The Vikos Gorge is characterized by its breathtaking natural beauty, with vertical cliffs that drop down to the Voidomatis River, crystal clear waters, and dense vegetation. The gorge is home to a rich variety of flora and fauna, including several rare and endemic species. Visitors can hike along the numerous trails that crisscross the gorge, enjoying the stunning scenery and the peaceful atmosphere.

One of the most popular trails is the Vikos Gorge Trail, which follows the course of the Voidomatis River and takes hikers through forests of oak and pine, over stone bridges, and past picturesque stone villages. The trail is relatively easy to navigate, and takes around six hours to complete.

The Vikos Gorge is also home to several traditional stone-built villages, including Monodendri, which is perched on a cliff overlooking the gorge, and is a popular base for exploring the area. The village has a number of traditional tavernas where visitors can sample local cuisine, as well as a number of small guesthouses and hotels.
