Belgrade Fortress (Beogradska Tvrdava)

Worth it if you're into history and want a proper walk around ramparts with actual views over the Danube—the 4.8 rating from 327 reviews suggests people aren't overselling it. Skip the guided tours unless you want context; the fortress itself is walkable solo and you'll dodge crowds by going mid-morning on a weekday, which also means you pay once and spend as long as you like.
