Did you know that in Germany (at North Rhine-Westphalia, to be specific), an old nuclear power plant has been converted to a theme park? You can climb up the cooling tower and enjoy the gigantic swings inside it.
If this got you curious, let me tell you that you're just at the right place on the internet to add that one quirky and out-worldly experience to your travel list at the best theme parks in the world.
Travelling the distance to visit a theme park might sound borderline old school but my travel research suggests otherwise. To give a twist to the list, I have steered clear off the "Disney theme parks" around the world and hunted for the most imaginative and unconventional theme parks in the world that can give even adults an immersive experience.
