The blueberry-coloured Moomin House is the main attraction of the park, where guests are permitted to visit all five storeys. The full-size moominhouse was built in 1993 to look like Jansson's own earlier drawings of the house. Hemulen's house is located next to the Moomin House. It is also possible to go to, for example, Moominmamma's kitchen, the fire station, Snufkin's camp, and Moominpappa's boat. Visitors can also meet Moomin characters around the park or the Witch in her cottage.

Moomin World is not a traditional amusement park, as it does not have any rides. There are numerous activities and paths including Toffle's Path with the Witch's Labyrinth, The Hattifatteners' Cave and The Groke's House. There are also performances in the covered outdoor Moomin theatre Emma.

Moomin World is open daily from mid-June to mid-August.

Moomin World was called the world's fourth best theme park for children according to The Independent on Sunday (October 2005). Moomin World was elected as the domestic travel destination of 2005 (Matkamessut, Finnish Travel Fair 2006). Moomin World won the Golden Pony Award 2007 by The Games & Parks Industry magazine: the jury said that "Moomin World is welcoming, well themed and full of educational content."

Metsä ('forest' in Finnish) is a Nordic-themed entertainment park in Hanno city, northwest of Tokyo, Japan. It was opened in March 2019, and includes an area called Moominvalley Park, the first Moomin theme park to be located outside Finland. Metsä was initially planned to start operation in 2015 for the 100th birth year of Tove Jansson, but on June 30, 2015, it was announced that this would be delayed to 2017. On December 6, 2016, the opening date was further pushed back to spring 2019.
