Ready to ride wood?


One of KAYU’s lead objectives is to be very committed to the environment and reducing their footprint on the planet, therefore we use balsa wood.  Originating from the balsa tree, also known as Ocroma Pyramidale.

The lightweight nature of balsa, makes it the perfect material for a light wooden surfboard. 


KAYU Surfboards are manufactured to appeal the driven beginner, all the way to the cultured advanced surfer. Known for its low density and high strength, it is also incredibly buoyant.

When looked after carefully, these surfboards are designed to last a lifetime.


KAYU is wood in Indonesian and Balinese languages. Our roots are in Indonesia and all our raw materials are sourced from local small scale plantations in East Java.

We effectively source our own materials, while our true suppliers are those that cultivate the balsa tree.

  • I thought the heads turning on the beach would be enough happiness out of this board. But then I felt it in the sea. From the first paddle, to the second wave, to the third bottom turn, each experience on the 5’4″ Little Fish was incredible. I also love how light and durable the board is, without compromising on quality. The team at Kayu were also brilliant; so passionate about their craft, yet so humble. I learned so much from them when buying my board and was so happy with the fast, efficient service.

  • KAYU boards are simply amazing and I love the feeling of riding a wooden board they are so light. The contact with the water is just pure happiness, I have the Varuna Short board and a fish from KAYU: 2 different boards for small and big swell. I’m so happy not to contaminate the ocean anymore with a foam board. Thanks again KAYU surfboards!!”

  • I guess you would call me a Silver Surfer – I’ve ridden a lot of boards over the years, some outstanding and some barely worth putting on the water. But I have to say Kayu gives you a whole new experience. It’s not just an incredible ride, cool and sensitive when you need that, powerful and dynamic when you need that, but it’s a beautiful thing in its own right. For years I’ve hated to be part of a sport that loves the environment but ends up creating a load of polyester trash. We shouldn’t be doing that anymore.
    Kayu is a thing of beauty and totally in tune with sustainability. For me, there’s no looking back.
    I should add that the Kayu people are great to deal with – very knowledgeable and helpful – and I’d recommend a visit to their shop when you are in Bali.

  • When I became aware of how unsustainable surfboard materials are in the modern surfing world, and seeing the health of our Oceans deteriorate day by day, I asked myself which sacrifices I would be willing to make so I can give back to the planet.

    That’s how I gave wooden surfboards a shot and found out about KAYU surfboards in Bali.

    I got myself a “little fish” 5,5 with a quad set up. I ordered this board for the smaller days; I have surfed it in up to 6 ft waves and it has proven itself to be the fastest board I’ve ever ridden. Not only that, it is also a real wave catcher, I can take off from a lot deeper and make it through fast sections more than I usually do. It’s ideal for big carves and great for tubes if you can manage its speed. 

    Did I sacrifice performance to surf wood? I don’t think so. A pro surfer would argue on that part though, I feel that if you don’t belong to the 5% surfing elite or that you goal is not to throw big airs, then it won’t affect your surfing progression but rather enhances it. It’s a fraction above the average weight compared to standard performance surfboards but literally unnoticeable in the water, however it is indestructible and this board may last you 20 years rather than 1-2 years. I highly recommend KAYU surfboards, it is well worth the investment.

  • My love for the beach, the sea and surfing has increased my concern and passion for the environment. For a few years now, I and my wife have started this journey towards sustainable living. From our way of life in the city here in the Philippines to how we travel and surf, we started learning about ways how to reduce our carbon footprint and sustain the beautiful things nature provides, especially the ocean. I learned that most surfboards now are made cheaper with synthetic materials that take centuries to decompose. So for my second board, I wanted something different. Coming from a 9-foot log, I wanted to transition to a fish. And I wanted it to be made of wood. I waited until we travelled to Bali for the first time for our overdue honeymoon. Upon researching, I discovered Kayu surfboards from another Filipina long boarder.

    2 things I love about Kayu hollow wooden surfboards is that they grow their own wood and their holistic sustainable concept. The use of Balsa wood, from the fast growing Indonesian Balsa tree, makes their boards very light, yet very durable, 2 important things for a surfboard. And by growing their own Balsa trees for harvesting, they not only reduce their footprint on the planet, they also help uplift the local communities that grow, harvest and manufacture their wood. When i got to the Canggu shop, aside from these facts I’ve read online and finally seeing the craftsmanship of the boards up close, it is also by discovering the passion of the people behind the boards that convinced me that this is going to be my next board. Now, every time I surf with my 6” Papillion fish, I will always be reminded with this mindset that there is always a way to enjoy a sustainable life.

    It’s still a long journey, both towards sustainable living and riding my fish, but so far my Papillon has been teaching me all good stuff.
