Shimanami Kaido Bikeway runs between Onomichi in Hiroshima prefecture and Imabari in Ehime, allowing cyclists to hop across several islands of the Seto Inland Sea.
This 70km bikeway connects Onomichi with the islands of Mukaishima, Innoshima (for the pirate Suigun Castle), Ikuchijima (for Kosan-ji), Omishima, Hakatajima, and Oshima, ending in Imabari on Shikoku. You're welcome to walk or jog any length of the bridge, but cycling is the best way to go. The route consists of wide dedicated lanes for bikes and pedestrians, typically alongside but separated from the car roadway. Special bike lanes have been created to provide reasonable approaches to each of the modern bridges connecting the islands.
