About Tori Ike
Tori Ike is a Shimoji Island boat dive that runs through an underwater tunnel into a pond system on land, making the route as much the attraction as the destination. The dive mixes dark cavern passage, surface time in the pond, and a return through layered fresh and salt water, so buoyancy, equalization, and a calm pace matter more than covering distance.
