There are many ways to explore the seven mountains that surround the picturesque UNESCO World Heritage city of Bergen on Norway’s fjord-studded west coast. To break up the monotony of the windowless tunnel, there are a variety of art installations throughout, as well as different colors and lighting to help users place where they are on the journey and offer a sense of direction. This former train tunnel is now a passageway for cyclists, runners and walkers and is part of the 250-mile Palouse to Cascades State Park Trail
