Finland is a big country, and you'll need a map of its roads and cities.
You can travel on your own, rent a car, or use the country's transportation system, but a map of Finland will help you either way. Any traveler knows that the more detailed the map, the more successful the trip, and in a country like Finland, even more so.
Hundreds of lakes, forests, small and little-known towns and cities hold their own surprises. You can go fishing in the center of Finland, or admire the northern lights in the north, but you'll need to have a map of the country with you. Whether it's in paper or loaded into your smartphone's memory is another matter.
