Fodor's Expert Review Suoi Tien

Believed to be the world's only Buddhist-themed amusement park, Suoi Tien (the name means Fairy Stream) is certainly one of the quirkiest. On the outskirts of Ho Chi Minh City, about 20 km (12 miles) from District 1 and behind a giant pair of tusks, it's a vast, sometimes downright odd, complex that contains an amazing diversity of attractions, from waterslides, crocodiles, and dolphins—thankfully, not all in the same place—to graphic depictions of hell, though there are not many signs in English to explain the more bizarre exhibits. There's also an ice palace, 4-D movie theater, fun fair rides for smaller kids, a go-kart circuit, and quad biking. Allocate a whole day to exploring the complex, and arrive early to get the land-based activities done before things heat up too much, then cool down in the water park, with its range of slides and pools to suit all ages. Food and drink kiosks can be found throughout the park.

The small zoo is depressing and best avoided.

Doing the water park and then exploring the theme park is going to be a huge day out, so it's probably better to choose one or the other for a day trip.
