If you’re looking for a day-trip destination, we’ve got some suggestions. Sitting 35 miles away, St. Petersburg is worth the drive. Among the first stops you make here should be Mariinsky Theatre, C-189 Submarine Museum and Yusupov Palace. Locals will also probably point you in the direction of Vyborg, 45 miles away. If you only have time for one attraction here, make sure it’s Vyborg Castle. (But we’re also huge fans of Red Square and Lenin’s House Museum.)
