Shang Shun World

Located in Miaoli County, Shang Shun World is Taiwan's self-proclaimed biggest indoor amusement park.  In a 6 story building, connected to a shopping mall and a hotel, Shang Shun World provides a full day of indoor fun for kids 2 and above.  With a merry-go'round on the first floor, as you go higher in the floor, the more suitable the attractions are for older kids.  There are bumper car rides, zip lines, play gyms, VR rides, and rock climbing facilities.  An entrance for the day will get you most of the rides for free, although there are some other rides you have to pay extra for.

It is a 90 minute drive from Taipei and suitable for a day trip.
