Guild Wars 2

I’ve reached a point in the story that requires me to get to an area east of Auric Basin. The quest log says (POSSIBLE SPOILER AHEAD):
The Predator’s Path:
Find a way to reunite with your team.
Find Taimi’s first message.

But I have no idea how to get to that area (shown in the picture).
BTW, I already have glider updraft mastered.

kitten , I think I found it, There’s a cave near the crossroad to the north with bouncing mushrooms.
