There are several ways to reach Peterhof Palace from Saint Petersburg. If you arrive by bus, train or private tour, you will approach the southern facade of the Grand Palace from the Upper Garden. A scenic alternative is catching a hydrofoil near the Hermitage. After riding across the Gulf of Finland, you will arrive at the Marine Canal in the Lower Park. Walking through the Upper Garden is free. Prices for all other sections vary depending upon which of the ten museums you wish to explore. The peak season is May through September. Crowds are heaviest during the weekend and midday during the week. The fewest tourists visit on Monday mornings.
