Popular Northern Lights destinations include Tromsø (Norway), Abisko (Sweden), Rovaniemi (Finland), and dark-sky areas outside Reykjavik (Iceland). Abisko is often more affordable than Tromsø. To save money, travel in early spring (February–March) or autumn (September–October), stay just outside major towns, and consider hostels or Airbnbs instead of hotels. Comparing tours and booking flights early can also reduce costs. Each location offers winter activities like husky sledding and snowshoeing alongside aurora viewing.
