WILD HEARTS

The Glider is unlocked when you move onto the second island and complete the quest "Hunt the Spineglider." The Glider can be placed on the ground by holding " + " and it'll cost you 3x Threads to place.

I found a great spot to get the 150m glide at the most northern point on the first island "Harugasumi Way." Climb to the very top of the "Tumbledown Hillside Shrine," place a Glider on the top and jump off facing east. As you glide down ensure you aim for the cave entrance to land on the lowest point. The achievement should pop when you land.

Note: Progressing the main story a little further on will unlock a camp at this location too. Which is handy for fast travelling to!

See video guide for map:

Once you got the Glider, teleport back to the village and follow my walkthrough video below. Easy~
