[Enjoy "Water Play at Moominvalley" this summer!]
1. Hobgoblin's Magical Splash Zone

In the story, the black top hat has the magical power to change the appearance of anyone who puts it inside, and when it falls into Moominvalley, a series of incidents occur in "The Hobgoblin's Magic Hat." The children have a blast watching the water suddenly spray up from inside!
② "Splash Creek"

Soft flowing water, sparkling soap bubbles, and sunlight surround you as you see children smiling and frolicking everywhere.
End of period
③ "Little My's Sunflower Mist Terrace"

Sunflowers spread across the entire terrace, as far as the eye can see. A soft, cool mist gently softens the summer sun. Adults can also relax and enjoy a soothing moment here.
4. "The Mysterious Mist Road of Moominvalley"

During the day, the rainbow-colored scenery created by the sunlight filtering through the trees and the mist is truly fantastical. The soothing scent of the forest will make you feel as if you are walking through a storybook.
4. Moominvalley's Splash Pool

A new area has been opened that will captivate both children and adults, giving the feeling that you are playing on the lake.

Attention point
The sound of a harmonica can be heard on the boardwalk leading to the "Lake Terrace"...
Watch the fireworks from the "Lake Terrace"!
During the "Moominvalley Lakeside Fireworks Festival" and "metsä Nordic Fireworks 2025," which will brilliantly light up the summer night sky and lake surface, the "Lakeside Terrace" will be open as a fireworks viewing area, where you can enjoy the spectacular entertainment of light and music reflected on the water's surface, which is different from the view seen from the front on the lakeshore.
The boardwalk is also fantastically lit up at night!
More fountains at "Moominvalley's Splash Pool"!
Welcome to a fantastic night! Summer illuminations
*Illumination times: From sunset until closing time.
