The defunct Wonder World Extreme Park was an amusement park in northern Bangkok which ran from 2006 to 2011. Attractions included two roller coasters, named 'Tornado' & 'Slalom' respectively, a ferris wheel, go cart track, free drop, and a few other rides. It closed in 2011 due to the infamous floods that year, but also has some local competition in the form of Siam Park City (or 'Suan Siam'), which offers a water park & a wider selection of rides. The park is not technically abandoned as the grounds are kept for the regular trade shows & exhibitions held there.

I lived in that area of Bangkok on Nawamin road for a few years but never visited the park, though I drove by it often. It usually had business in the evenings, especially on weekends. The expense of repairing the damaged rides after the 2011 floods must have been too great.
