The Treska River, flowing through North Macedonia's Skopje region, is an ideal spot for fly fishing enthusiasts. The river serves as a habitat for a range of fish species, such as brown trout, grayling, chubs, and European eels, creating a diverse and engaging angling experience. The picturesque Matka Canyon, where the river runs through, offers a serene setting for a day of fly fishing. Make sure to obtain the necessary permits before casting your line.
