Yosemite
I only spent 2 days in Yosemite (as part of a Road Trip) but they were 2 of the most memorable days of my life.
The collosal scale and natural beauty of this place forces you to use words like biblical when describing it to people yet to visit this part of the world.
It was difficult to stop taking photos of this stunning landscape. It’s no wonder that Ansel Adams devoted most of his life to that this place.
