A spring cycling trip to the Seto Inland Sea is a wonderful choice, with perfect weather. Remember to rent an electric-assisted bike because there are many ups and downs, which can be quite tiring.
It's recommended to take a ferry to one of the islands first so you don't have to ride too far, but you can still enjoy the joy of crossing the sea between small islands.
There are fewer restaurants on the islands, so pay attention to their locations.
