I am going to have to go with the obvious, easy answer.
I like the beach! Both from a scientific viewpoint because there is a large diversity of species to see, and that you can move a few dozen feet and see an entirely different group of species. And also, of course, from the point of view of aesthetics, the ocean and cliffs and long beaches are just nice to look at.
Of course, when I actually have lived close to the ocean, I have lost my appreciation of it quickly—it is different when you see it every day. I would still say that it would be my first choice, though.
