7. A Month On a Glacier
High school and college kids looking for the trip of a lifetime should check out the National Outdoor Leadership School, which offers extreme vacation destinations all over the world, including a month long course that takes students to South-central Alaska, also known as “the mountain kingdom of North America.” Here, young adults 17 and older will find themselves traversing some of the most stunning and rough terrain in the world. It’s a life-altering chance to push your limits and see what you’re really made of.

8. Traverse the Great Wall of China
Don’t just do the typical tourist pitstop to the Great Wall as a day trip from Beijing. Walk the engineering marvel like the Mongols of old. Starting from Gubeikou, hike from tower to tower in a spectacular multi-day trek. Experience authentic Chinese culture at rural guesthouses in villages along the way. Some parts of the wall are restored, but other areas are the original stones so you’re literally walking in the footsteps of the ancients.
