You'll find good opportunities to get this as you work towards "The adventure of a lifetime" achievement, but if you are having trouble the place I got it was the Yotei Snow Park Challenge. In this challenge you'll have the opportunity to hit 4 boxes right at the start, so if you mess it up you can easily restart. Veer to the left when you start and you'll see a section with multiple boxes.
For the last box in the sequence, hold the right stick to the left when you jump so that you make it on.
Let me know if you have any questions or suggestions to improve this solution.
