Registration Opens for the World’s Happiest 24 km Downhill Swim

Amazing event in one of the most beautiful national parks in Finland

Released October 01, 2024

Registration opens today for the highly anticipated Downhill Swim, scheduled for July 19, 2025, amidst the breathtaking landscapes of Finnish Lapland—the happiest country in the world. Held in the crystal-clear waters of the Oulanka River in Kuusamo, this exhilarating event invites swimmers to embark on an unforgettable journey through one of Finland’s most beautiful national parks.

Now entering its fifth year, the Downhill Swim is renowned for its joyful atmosphere and stunning natural surroundings. In the summer of 2024, the President of Finland, Alexander Stubb, participated in the event with his spouse Suzanne Innes-Stubb. The experience was unforgettable for the presidential couple as well.

“This event is more than just a competition—it’s a true connection with nature. Participants genuinely immerse themselves in some of the world’s purest air and landscapes. The sandy banks, sightings of reindeer, and the breathtaking scenery of Oulanka National Park make this an unforgettable experience,” says Kalle Kotiranta, Event Director.

The event is open to swimmers of all levels, from seasoned competitors to those seeking a leisurely adventure. There are a limited number of places available for pre-registration for both the 12 km and 24 km courses.
“Swimming skills are essential for navigating this event,” continues Kotiranta. But the current helps propel you forward. Even a small current makes a significant difference—saving half a minute per hundred meters.”

Beyond the swim, participants and spectators can enjoy a range of post-race festivities, including traditional Finnish saunas, the magic of the midnight sun, and local cuisine.

“Ruka-Kuusamo offers a wide range of activities for outdoor and sports enthusiasts year-round, and this event is an excellent opportunity for us to show our guest the unique nature of Ruka-Kuusamo area,” says Janne-Juhani Haarma, CEO of Ruka-Kuusamo Tourist Association. 

Swim and accommodation packages are available.
