The problem with the whirlpools is that they are hit and miss based on the tides. And only being in Japan for two weeks, I am not going to wait half the day or make a special trip to see them. So, you take your chance. And... we missed. It is a nice park and a great view of the strait and the bridge. But, it is very touristed and overly hyped. Since there was no whirlpool that morning, we didn't pay to go out on the walkway below the bridge. If you are coming through and have an hour, it is worth stopping on the chance of seeing the whirlpools and to enjoy the view.
If you are driving you will have to pay for parking.
