In most European cities, the sightseeing routine is famously predictable: comfortable shoes, a glowing map on a smartphone, and a slow shuffle from monument to monument. You look up, take a photo, and move on. Meanwhile, just below street level, an entirely different version of the city is quietly flowing past.
In hubs across Northern Europe, including Copenhagen, Stockholm, Berlin, Oslo, and Helsinki, canals and harbors offer front-row seats to Europe’s most stunning architecture and hidden waterfront neighborhoods. Through GreenKayak, an environmental non-profit organization, you can explore these waterways for free — by kayak! The deal is simple: in exchange for a complimentary paddle, it asks only that you scoop up any floating trash you encounter and share a photo of your experience on social media using #GreenKayak to spread the movement.
How it works: from app to water
The beauty of GreenKayak lies in its accessibility. Its bright green tandem kayaks are stationed at 41 locations across northern Europe in five countries at cafés, museums, and nature centers. Check to see if there are GreenKayaks where your next adventure awaits!
The process is simple, all you need is the free GreenKayak app, which serves as your instruction center for the experience.
- Book your slot: Choose your city, date, and time directly in the app.
- Arrive and check-in: When you arrive at your starting point, the app provides your specific next steps.
- Self-service or hosted: Depending on the location, you might be greeted by a local host or use a self-service system. In either case, all necessary instructions, from safety tips to equipment locations, are delivered right to your phone.
- Gear up: You’ll be provided with life jackets, paddles, a trash grabber, and a bucket. These kayaks are stable and beginner friendly. So, if you can sit and paddle, you’re ready to go!
A different perspective on a city
Once you push off, you’ll find yourself gliding under bridges that most visitors only see from above. You might drift past floating saunas, houseboats, or quiet gardens that remain hidden from those on foot.
Whether in Stockholm, navigating toward the scenic Fjäderholmarna Islands, or in Copenhagen, seeing the Little Mermaid from the water, you can skip the hassle of traditional sightseeing and go GreenKayak instead. Somewhere along the way, you’ll spot a plastic bottle or a stray wrapper. As you lean out to scoop it up, the nature of your trip shifts — you’re no longer just a tourist passing through; you’re an active contributor to the city's health.
The final weigh-in
At the end of your session, you return to the dock and weigh your collection. This final number is logged in the app, contributing to a massive collective effort that has already removed more than 150 tons of waste from European waterways.
Traveler Tip: This activity is seasonal, typically running from spring through early autumn. Be sure to dress for the weather and remember that basic swimming ability is required. Children are welcome to join with an adult, making this a perfect, sustainable family adventure.
Responsible travel doesn’t have to be a chore. Sometimes, it’s as straightforward as swapping a walking tour for a paddle and trading a traditional souvenir for the quiet satisfaction of leaving a city better than you found it.
