In my year of living in Scotland, Scots had always told me to not go to Aberdeen. "There's nothing there. It's ugly. It's boring. It's dead depressing", they would say. But in my current trip to Scotland, I would have to say I really enjoy the city. The building facades line up neatly along the streets, like a giant hedge maze. Even with the grey buildings, and grey skies, it still has a lively atmosphere- pedestrians, cars, and motorbikes scurry (and at night, stumble) the cobblestoned streets.
I would definitely recommend a weekend stop here- it's certainly not heaving with daytime activities, but there are certainly some excellent medieval-style pubs in renovated churches (delightful sacrilege) and authentic international cuisine from India, Italy, and Spain in particular. It's also incredibly close to the Scottish and Castle trails, and just an hour from the highlands... so it's an excellent place to put your feet up before going on an adventure!
