With this guide, you'll set sail to Europe's most prosperous corner, a smorgasbord of Viking ships, deep green fjords, stave churches, brooding castles, and colorful farmhouses. Explore the sleek, modern capital cities of Copenhagen, Oslo, Stockholm, Helsinki, and Tallinn. Cruise through Stockholm's scenic archipelago, and sample the Baltic charms of Tallinn. Delve deep into Norway's scenic Sognefjord and bike through the idyllic Danish countryside on the castaway island of Aero. And take some time out from sightseeing to get your blood pumping in a steamy Finnish sauna.
