The Hawaiian Island of Kauai. If you can climb the green volcano all the
way up to above the clouds, its (like) going to heaven.
The MYST series of games. Beautiful scenery and interesting machines
and books that make you travel through time. Nothing makes you die
so you can just wander around in them.
Probably Secondlife.com but I never tried it, since I have my own version.
3D pictures. If you search the internet you can find out how to easily make
all different kinds with a digital camera. (and many other ways)
Music...,
And other recordings (of certain natural places like beach, waterfalls,
rain forests, babbling streams, ... even stereo recordings made in places
with people, all these so realistic that you can close your eyes and think
you are in those places).
Real castles (mansions) and gardens.
Hedge mazes.
Sculpture gardens, sometimes are like being on another planet with alien
machines.
Getting lost in some of those places on purpose.
Secondlife? I never tried it but I do like Virtual Reality Worlds in general.
Certain kinds of CAD systems let you design buildings and then explore
them, although it is probably easier to do the same thing with the level
editor of a raycasting engine, or any LEGO game that might have the
feature of letting you build something and then shrink yourself so you
can wander around inside of it. I used to wish I had that all the time,
but I used my imagination instead. If the LEGO games do not have
the feature of building and going inside things, then the same effect
can be done with an endoscope, but it is a very expensive thing to
use as a toy.
Landscape synthesizers. Terragen is freeware. Pandromeda is the one
that made the Genesis Planet in the Star Trek movie (#2?) with Kahn.
I think those are both still available and can be used to 'fly".
This site is very old. When it was made, the web still had background music
until the music police put up STOP signs. It doesn't work for me anymore
but who knows it might work for some people. "FLYING DREAM".

The mouse has some control, if anything happens at all.
Flight Simulator? Google Earth? Google Mars?
Many people including myself have wished for a way to record and
share DREAMS. It is not totally impossible. Good artists "take pictures
of dream worlds" and show them to people. The art from the vinyl
albums Yessongs and Close To The Edge (and other Yes albums and
also Asia album) were drawn or painted by Roger Dean, and many
people think a place on Pandora in Avatar was "borrowed" from his art.
Try Youtube search for "Roger Dean Animated".
Many people have longed to enter and visit the worlds he painted.
Recommended video "Beyond the Mind's Eye", is Virtual Reality type cgi
demos made before any of you heard of the www or Pixar. Lots of flying
in cgi worlds in it.
Recommended video with lots of music interest, bands of impossible
cgi instruments playing themselves in ANIMUSIC. There is one with lots
of ping pong balls shooting out of PVC pipes and hitting drums and bells
and horns and stuff, which is probably the most famous.
If you like H@rry P0tter and wish you could go to H0gw@rts then
try the video games. I tried one for Nintendo Wii. I obfuscated the
name because the author and publisher have been very aggressive
against people who as fans have created related art, and that is why
I can't find a certain very interesting thing anywhere on the internet.
But the game may be the next best thing to what's missing on the internet.
Daydreaming, Lucid Dreaming, Regular Dreaming,
Making sand castles (with SUNSCREEN on!), or clay castles, or LEGO castles.
Building and then being in a tree house, as long as it is safe.
ETC.
