Skip trash to Witherbark in The Everbloom (Aimed towards CM)

The search engine isn't working at the moment, but I've checked the forums everyday for things, and haven't spotted this so that's why I post.

You can skip the first trash for Witherbark, which can be useful just for skipping but also for Challenge Modes. It saved me quite a few minutes and got silver on first try.
You go up through this way, jumping of course.: (If you got someone with 2 man mount then use it to get people up)
