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.

There are two additional drop-off-only location in Imabari. Bike depots have a variety of bicycles including 8-speed road bikes, 3-speed "upright" bikes, and electric assist bikes (electric assist must be returned to the original depot it was rented from).

On weekends, you should plan to rent your bike before 10am if you are starting from Onomichi. On the Imabari side, Sunrise Itoyama shop is the closest to the bikeway, but the public transportation from/to the city is quite limited. There is few buses from Imabari JR station (leaving Sunrise Itoyama at 9AM, 10:20AM, 1:42PM, 4:14PM and 6:17PM, and leaving JR station at 8:38AM, 9:58AM, 1:20PM, 3:52PM and 5:55, in 2015). Alternatively, Hashihama station is less than 2km from Sunrise Itoyama (5 minutes to Imabari station, about every hour).

An excellent English language brochure is available at the bike depots and online here . The brochure provides riders with side-trip directions to sights on each island and alternate routes for those who desire more strenuous rides. The brochure also has information on rest stops, bike depot locations, public transport (if you get tired) and other facilities and there are many choices along the way for lunch, snacks, and other stops. If staying overnight in Onomichi, it is recommended that you pick up a brochure from the bike depot the night before your trip.
The Green Hill Hotel is also the location of the ferry connecting Onomichi with Mukaishima, Innoshima, and Ikuchijima/Setoda. Serious bikers intent on completing the route in a day could do so, but the route is best enjoyed over the course of two days or in one day by taking a ferry from Onomichi to Setoda (bypassing the two most rural islands on the route). Ferries leave Onomichi once an hour starting at 7:20 in the morning; the trip to Setoda is 40 minutes. Tickets are available in the ferry terminal behind the Green Hill Hotel.
The main route is generally flat except for reasonable and well-graded approaches to the bridges and one large hill on Oshima Island. The whole route is free of charge for cyclists and pedestrians.
