RÉSERVE NATURELLE DE JASEN

Matka Canyon is part of this nature reserve (Резерват Јасен/Reservat Jansen). Created in 1958, this one covers 31,127 ha (311 ^km2) along the Treska River with superb scenery between the artificial Kozjak lake and the Matka canyon. It includes several entrances and marked hiking trails in the mountains on either side of the river. However, the website of the organization in charge of the reserve is in Macedonian only.
