Don't spend your time sitting in port. Opt for a sightseeing tour of St Petersburg and nearby Peterhof instead. Visit the city's top must-see attractions from the comfort of an air-conditioned vehicle, including the onion-domed Church on Our Savior on Spilled Blood, the Hermitage Museum and Palace Square. Enjoy a cruise along the Neva River and take a trip to Peterhof, a summer palace known as the 'Russian Versailles' due to its impressive gardens and fountains. Return to St Petersburg via high-speed hydrofoil boat, weather-permitting.
