This Luxury Train Journey Is Now Going Deeper Into the Arctic Circle’s Northern Landscapes

It's now possible to take a trio of stunning Norwegian train rides all on one luxury trip. Sustainable upscale tour company Up Norway is offering an extension on its already spectacular Arctic Circle Express tour. It allows travelers to go even further north to Lofoten and Narvik, and experience the Ofoten Line (Ofotbanen) — one of the nation’s standout railways in addition to Flåm and Rauma, both also on the itinerary.

“This enhanced 15-night itinerary invites discerning travelers to embark on an immersive adventure through Norway's captivating Northern landscapes, unveiling hidden gems and rich cultural experiences along the way,” the company said in a release provided to Travel + Leisure. “In Lofoten, with the added trip extension, travelers can enjoy remote villages, a dramatic scenic route, adrenaline-pumping arctic surfing, and international art collections.”
