I've fortunately gotten to experience a good variety of theme parks in my lifetime, and I enjoyed my time in every one of them. The most common ones are in the U.S., of course, such as Disneyland and Universal Studios, etc., but I know there are theme parks in some countries that aren't as famous, but still very fun, so I thought we could discuss some of the more obscure ones in this thread. Still, if the popular ones are the only ones you have experience with, then please still do share your experience with us here. My pick as an obscure theme park that is still worth a visit would be Hong Kong's Ocean Park. I admit that it might not be good enough to serve as a reason for travelling to that country like Disneyland would, but still I think it is worth dropping by there if you are already in HK anyway. The theme is as the name says, which is ocean life, so you could go see gigantic aquariums filled with many interesting underwater species as well as go on some common rides like ferris wheels and carousels, etc.
