This is the list of places, buildings things I've always wanted to see - some I've managed to, some I'm still planning, and some are still a long way off.
Engineering
Active Mine
One with a very long ride down in a lift.
Aircraft Carrier
Active would be great, but just an old one is fine.
Airplane Factory
Airliners, fighter jets, or perhaps tiny planes.
Anechoic Chamber
Not big, but still quite impressive.
Deep Space Observatory
You know, the really high up ones. Full of science.
Fission Reactor
Preferably without too much radiation exposure
Fusion Reactor
Big, round and very, very hot.
Visited JET, May 2010
Huge Dam
We're talking giant here. Preferably with an inside.
Oil Rig
Troll A would be amazing, as it has hollow legs.
Particle Accelerator
Big, round, and very, very cold.
Visited Diamond Light Source, March 2012
Rocket Launch
Something reasonably large. Moon launch best.
Tallest Building in the World
Waiting until this is no longer in Dubai.
Top of a Wind Turbine
I've stood underneath, but not up top.
Nature
Antarctica
I'd include the other continents, but they're too easy.

Something that needs proper equipment to reach
Desert
Sand dunes! Dune buggies!
Fijords
Norway, New Zealand, something similar.

A continuously-burning hole in the desert

A nice big one, full of ice.

Of the volcanic kind, naturally

Specifically, the ice caves.

Why not? It's not that far away...

Where there's no other land in sight

We're talking full-on lava lake here.
