A secluded place is isolated, away from other people. It's quiet, and there's not a lot going on.
Sometimes you need to get away from it all to someplace where no one will find you. What you seek is a secluded area where you can be alone. A secluded spot conjures the image of someplace removed from the intrusions of life. A writer might want to be secluded so she can get work done, and a couple might want to be secluded so they can spend time together. When you're secluded, there aren't many other people or distractions.
