OBOKE-KYO & KOBOKE-KYO

The Chasms and Koboke chasms, near the entrance of the Iya Valley upstream of the Yoshino river, have been registered as a national treasure since 2014. The gorges of Oboke are mainly known for the turquoise colour of water and for the large rocks bordering the river, natural perches for many birds. The Yoshino River is one of the best rafting spots in Japan, but the descent can also take place with a small cruise boat. It stretches over 194 kilometres from the Ichizuchi mountain range to Tokushima Bay.
