If you’re looking for day-trip inspiration, we’ve got a couple of suggestions. Sitting 30 miles away, St. Petersburg is worth getting in the car for. Explore the area starting with Mariinsky Theatre, C-189 Submarine Museum and Yusupov Palace. Locals are also likely to point you in the direction of Vyborg, 45 miles away. If you only see one thing here, make sure it’s Vyborg Castle. (But we’re also huge fans of Red Square and Lenin’s House Museum.)
