This steep-sided, beautifully green river valley, used as a location in the Turkish film Bal (Honey), is a wonderful place to experience traditional Hemşin life. Along the 7km stretch from Çamlıhemşin to Şenyuva, winch wires, for hoisting goods up to remote mountain houses, criss-cross the thickly forested slopes above the road. Look for the hillside mansions built in the early 20th century by families enriched by their menfolk working as chefs and bakers in pre-revolutionary Russia.
Graceful arched stone bridges built in early Ottoman times cross the rushing Fırtına River 5km from Çamlıhemşin (just after Otel Doğa) and at Şenyuva. From the latter you'll get supreme bridge views from the cafe terrace 200m upstream.
The road up the valley is paved as far as Çat (1250m), a riverside hamlet that can be used as a trekking base, 27km from Çamlıhemşin.
