After convenient pickup at your accommodation in Helsinki, climb aboard your minivan and set off down the coastal road, passing the biggest Orthodox cathedral in Northern Europe, the Uspenski Cathedral. If it's summer, you can see the icebreaker ships docked along the shore before stopping for some photos in Senate Square with Helsinki Cathedral in the background. Take a walk to the local open-air market at Market Square.
Drive down the city's main thoroughfare, Mannerheim Street, which passes Finlandia Hall, the National Museum, and the Parliament House. Admire the architecture of Kiasma, the Helsinki Museum of Contemporary Art, then continue to the Opera House and the stadium used for the 1952 Olympics.
Disembark at Sibelius Park for some photos of the monument to composer Jean Sibelius, then continue to the famous church built into solid rock, the Temppeliaukio Church.
Your express tour of Helsinki ends with drop-off back at your accommodations or ship.
