The towers themselves no longer exist, parts were adapted for the Space Shuttle program, and one of the pads is now used by SpaceX. But we have the blueprints and photos, allowing 3D models to be made so we can tour the massive structure in the first person. And it's amazing to see the scale of hardware that was deployed to support this massive rocket.
The game 'Reentry - A Space Flight Simulator' includes a mode where you can explore this structure if you're maybe tired of following checklists and hunting for switches.
