Rymnio is the sole settlement within the municipality of Kozani, situated to the west of the Aliakmonas River. It is positioned along the southwestern shores of the artificial Polyfytou Lake and borders the Grevena region. The village is located approximately 28 kilometers south-southeast of Kozani and 15.5 kilometers southwest of Servia. To the west of Rymnio lies the Rymni Bridge, which, at 615 meters, is the second longest bridge spanning the artificial lake, following the High Bridge of Servia – Neraida, which measures 1,372 meters. Additionally, the Ilarion Dam and the PPC Hydroelectric Power Station are located 8.5 kilometers southwest of the village.

The area surrounding the bridge features a picturesque route, complemented by a diverse array of bird species that inhabit the vicinity. Many of these birds can be observed flying and nesting along the lake’s shoreline.

The region presents numerous opportunities for improvement and enhancement. It boasts unspoiled natural beauty and breathtaking landscapes, alongside a unique ecosystem where even olive trees flourish along its banks. The waters are home to 17 distinct species of fish, contributing to the area’s rich biodiversity.

The landscape features diverse elements including forests, small rivers and streams, beaches, trails, bridges, dams, archaeological sites, and scattered churches nestled in the surrounding hills. The exceptional flora and fauna are highlighted by a variety of plane and chestnut trees.

For those who have had the pleasure of visiting Palatanodasos in Rimnio, its stunning beauty is evident throughout the year. Notably, the area has remained undeveloped for 49 years, a fact that underscores its pristine condition.
