The Patsos Gorge, also known as the St. Antonios Gorge, is located north of the village Patsos in the Sivritos area. The gorge is about 5 km long and requires about 2 hours to traverse. At some points it's a bit of a scramble. It is a very green and shady gorge with a small river that runs all year round. There are spectacular rocks and at the start you can admire the St. Antonio's cave-church.
