During low tide, you can see the sand dunes on the beach, and you can see distant scenery and migratory birds through the telescope on the third floor. Plus, the telescopes are free, so you can see as much as you want. Compared to what you can do in the U.S. by inserting 25 coins and seeing it briefly, I am really satisfied. You can receive pamphlets with various information for free, but they are not in English, so you have to translate them using Google Lens.
