Yamay Discovery World Amusement Park in Taiwan (Lihpao Land)
Discovery World at Yamay Resort - now apparently called Lihpao Land - is located near Taichung; take the train to Houli Station. There is supposedly a free shuttle bus now, but last year (when it was Discovery World) I just grabbed a taxi to get to the park. There also appears to be a bus (#155) from Taichung that leaves every 30 minutes, so you might want to ask at their visitor's center. And if you're really interested in a long bus trip, there seems to be a bus from Taipei. Admission is NT$800, but a special price that is given to foreigners might be NT$590. Actually that happened at a lot of parks in Taiwan; don't be surprised to get a discount if you're obviously a westerner! The park opens at 9:00 and closes at 5:30 (later in summer and during Chinese new year). The park's English website is located here; it has good basic information but the Chinese-language site has bus timetables as well as a list of attractions that are scheduled to be closed during the day (even for an hour or so).
I should mention that while the park appears to have been rebranded this year, it doesn't have any new rides listed and all the rides I remember being there are still on the website.
