Adventure travel isn't everyone's dream.  All travel can actually be seen as meaningful adventures, if you chose to perceive a change of scenery that way.  Experience extreme altitudes, and deep sea diving expeditions into underwater caverns.  You can find the most challenging and unsual climates and cultures to stretch your sense of reality.  You can travel within or step far outside yourself. 

Some people travel based on their instincts, based on a recommended destination or, a sense of having visited a particular place before.  Some people travel based on a sense of necessity, to study,  find work, meet up with relatives, to live a dream, to pursue love or, to follow clues that bring one closer to a kind of destiny.  You may consider travel for any, all or no specific reasons.

As for me, I'm repeatedly asked about lasting impressions among the many continents and countries I have visited.  What compels me to migrate, to explore or seek new ways of learning?  I suppose that its in my blood like my Viking ancestors.  Yet, this instinct has been nurtured by my life choices.  I'm drawn to people.  I naturally go out of my way to forge human relationships. 

Developing friendships led me to write letters and share stories.  It wasn't enough to simply communicate at a distance.  I desired to experience places I had read and heard about.  I was motivated to create opportunities to discover them.  You don't dwell on why you think you can't. Rather, you just figure out how you will.
