It starts here at the south end of the encounter area. Then you hop up onto the rocks and make your way into the hallowed out log like so.
Once you get in there, lay down one of the lounge cushion toys (https://www.wowhead.com/item=116691/zhe ... ge-cushion). The toy comes from winter veil presents or they can be bought on the AH. Sit on it and when you hop off it, it'll put you past the wall. There's not much out there, but it's a neat place to explore. There's a bunch of huge toads that are unfortunately untameable along with some stags that are tameable. One of the neat things I found were some giant birds.
And some dryads.
