Burn O'Vat is a cool circular walk that starts at the car park near Ballater. You can check out this awesome geological feature called the Vat, which is like a big water-carved bowl that you can actually climb into using stepping stones. It's been a hit with visitors since Victorian times and has some cool history too. After exploring the Vat, the walk takes you through some nice pinewoods and open countryside before looping back to the car park. Great way to spend a couple of hours in the Cairngorms!
