What are examples of metaphors about the beach that i could use in a poem?

Some examples are:

- A beach is a safe harbor that can protect you from everyday wars

- It is a castle decorated with flowers/When in trouble, you can go up its towers.

- See the bright light overhead as well as the nonstopping flow of the vital energy that fulfills your soul.

P. S.: A metaphor is a way to explain what someone or something is like by comparing them, not in an explicit way, to something that reminds you of what or who you're talking about in the sense that it makes you feel the same way the original thing or person does and/or has features in common. Therefore, by stating that a beach is a castle (not like a castle, since it would constitute an explicit comparison), for example, one means it offers the same protection and has the same grandiosity a castle does. By mentioning you can observe the bright light overhead and the nonstopping flow of vital energy from the towers of the castle (the beach), one means that a beach has things we need in order to get through life: the light of the sun (the bright light overhead) and water (the nonstopping flow of vital energy).
