Might as well go twice…
If you go when the tide is in, you get the beautiful postcard view of the Torii standing in the water. If you go when the tide is out, you can actually walk right up to the Torii and touch it. The day I was there a lot of locals were out there in the mudflat digging for clams, and we were able to walk right up and touch the Torii. Granted, it look much more beautiful from afar, but it was a powerful feeling to lay hands on it.
Nice place, i would love to go back someday…
I have also heard that there is a kayak tour in the area that can take you up close, but I have never seen it. Could just be a rumor…
