No. It’s a small nation with a fairly well developed tourism infrastructure, so you’re not going to find Brigadoon or a secret glen.
There are places that are less crowded than the tourism honeypots like Edinburgh, Loch Lomond, Loch Ness or Skye. But if you found a beach or a road-end and you realised that you had the place to yourself, I would advise not telling anyone.
I know I wouldn’t. Not even on this website.
