Become immersed in Helsinki’s ground-breaking, eco-friendly architecture as a prelude to hiking through a national park. While driving through the lively capital, you will pass a collection of notable landmarks such as the Parliament House, National Museum and Finlandia Hall, a masterpiece that acclaimed Finnish architect Alvar Aalto designed. Still, few buildings are as striking as the Helsinki Central Library. Known as the Oodi, which means “ode,” in Finnish, the library offers much more than books. For instance, there are meeting spaces, music studios, restaurants and 3-D printers, all available to the general public. As you tour the Oodi, the guide will point its unusual aspects and describe the building’s energy efficiencies. You will understand why Finns are so passionate about preserving their natural resources when you see Nuuksio National Park. A wonderland of green forests, serene lakes and rugged crags, it makes an ideal setting for your hike and snack around the campfire.
