The Pavlla River originates near the village of Pavlla in Çamëria, in the southernmost part of Albania. The river flows in a sheltered bed through the plains of Mursia and Vrina, passes south of Lake Butrint and flows into the Ionian Sea, in the Gulf of Butrint.
The river is 50 km long, with an average height of 521 m and a catchment area of 374 km². The Karroqi stream is also the largest tributary, an extension of the Pavllai river which flows in a narrow valley, with steep and deep slopes, on limestone rocks. The plain area was previously swampy. With the reclamation of the Mursi and Vrina fields in 1959, it turned into fertile land.
