2. Northern Lights, Scandinavia
The Northern Lights, also known as the aurora borealis, light up the night sky with beautiful colors of green, pink, and purple. They are best seen in winter in places like Norway, Sweden, and Finland. The lights occur when solar particles hit Earth’s atmosphere. Along with watching the Northern Lights, visitors can enjoy winter activities like dog sledding, snowshoeing, and staying in ice hotels, making the trip truly memorable.
