Barnhill Rock Garden in Dundee is a chill spot with killer views of the River Tay. This award-winning park is like a mini botanical wonderland, packed with cool alpines, shrubs, and waterside plants. It's perfect for kicking back, taking in the scenery, and maybe spotting some wildlife. Plus, it's right by Broughty Ferry's beach and castle, so you can make a day of it. And the best part? It's free to enter, so you can save your pennies for an ice cream or two.
