Zusammenfassung:	PURPOSE: To provide a simply structural water tunnel that is able to pass a swimmer and a fish at a higher position than the water surface of a pool or the like. CONSTITUTION: This water tunnel body 10 is of arched tubular form and it is provided with two opening parts 12a and 12b at both the ends. In a state that the water tunnel is set up in a pool or the like, a central part of the body 10 is situated at a higher level than a water surface 16, and both these opening parts 12a and 12b are positioned at a lower level than the water surface 16. Subsequently, air in an inner part of the tubular body 10 is deaerated, and water is filled up in an inner part of the body 10. With this constitution, people and fishes are travelable from the opening part 12a on one side of the water tunnel body 10 to the opening parts 12b on the other by way of the higher position than the water surface 16 on the inside of the body 10.
