psycosynthesis that looks awesome minus the people 

Death valley. Mushrooms (With plenty off water, of course.) I have never been to that side of the U.S. but i imagine it would be quite the experience.
Wow, so beautiful. Natural wonders!!! Does that not prove fractals and mushrooms make up the shape of the world? hahahah
Gotta second the comments about Galapagos and Easter Island. I want to go to both of em... I wont be too far either.
But seriously, what about a underwater trip? Like imagine just popping something and going scuba diving in the great barrier reef, or in belize or galapagos or something. An hour or two underwater....
Edit, just saw the post two above me. But damn cool idea is it not?
^Ha, I was gonna write Machu Piccu.
But in truth- imagine doing a space-walk on DMT. Woot.
