Aurora Borealis 
Also known as The Northern Lights. 

The Northern Lights occur the most in the Northern hemisphere. It appears as a dancing sheet or dancing waves. You cannot predict when the Aurora Borealis will occur but the best months are March through April and September through October. The chances of seeing the Northern Lights increase as you get closer to the magnetic pole. 

Victoria Falls 

Victoria Falls is the largest waterfall in the world. It is located at the border between Zambia and Zimbabwe. The best ways to see the falls is from the air but walking along the trails is just as amazing. The best time of year to visit is June and July due to the two seasons Victoria Falls experiences, dry season and wet season.
