Haw Par Villa, a theme park with more than 1,000 statues and 150 giant dioramas that highlight Chinese myths and legends, might be the best value entertainment in Singapore. (It's free!)
Built in 1937 by the creators of Tiger Balm (the ubiquitous salve that soothes every ill), the park depicts scenes such as "Journey to the West," illustrates the virtues in parable-like form, and showcases statues of personages such as Laughing Buddha. Winding paths thread through the dioramas, allowing guests to pore over the details. Don't miss the 10 Courts of Hell display, which portrays the afterlife for wrongdoers—though I'd advise against taking young kids to this one, as it's explicit and creepy.
Some of the displays are a little run-down, but it's worth the MRT ride to be one of the few folks strolling this unique destination.
