The Kako River is the longest river in Hyogo, and where it widens toward the Seto Inland Sea at Kakogawa it becomes something quietly rewarding: a broad, shallow, braided channel of reed beds, gravel bars and shifting sandbanks. Herons and egrets stalk the shallows all year, and autumn and winter bring ducks, waders and other migrants down onto the open water. Level, well-surfaced paths run for kilometres along both banks, making this one of the easiest places in the prefecture for an unhurried walk or a flat cycle ride with a hire bike.

Tips
This is an everyday local landscape rather than a sight, so come for the walking and the birds rather than expecting facilities — bring binoculars, water and a hat, as the banks are open and shadeless. October to March is much the best window, when migrating waterfowl are on the water; early morning gives the calmest conditions and the most activity.
