Kakoperatos Gorge is originated in the village of Agios Vasilios. Throughout the length of the canyon flowing deep river Megalos interrupts lots of waterfalls and downs, so that it becomes unfit for hiking. In Greek Kakoperatos means "hard to pass." Kakoperatos, nevertheless, is popular with tourists. It is a beautiful and rugged canyon, ideal for canyoning. It has water most of the year and shapes 7-8 impressive waterfalls with deep ponds with clear turquoise waters, ideal for jumps.
