I have a few places I'd categorize like this. Anywhere where I can sit, look at, and hear the ocean would definitely be one of them. Another is in the woods near streams or rivers. I really like water apparently.
My dog absolutely LOVES water. He isn't comfortable in deep water but only because he didn't grow up with a body of water to learn in. Whenever we get close to water he needs to wade, to splash, to drink, to frolic. It's so cute and it is one of my favorite things to watch.
The following pics are of one of my perfect, relaxing places - my dog being there just makes it even better :)
