Where is the Hidden Walkway in Adventureland?
Ok, start at Adventureland entrance beside Pirates. Instead of walking through to either Pirates or PeterPan, walk down under the covered part. This is the start of the hidden walkway. Keep going straight across the second entrance to Adventureland, across to the round tables of the outdoor seating area of Au Chalet De La Marionnette restaurant. Instead of going into Fantasyland continue straight though the seating area, which takes you down the side of the restaurant. Follow the path, keeping the building on your left and you will see Adventureland on your right. Just keep going, following the side of the buildings and you will reach the third entrance of Adventureland. The next part is a bit more complicated. You need to walk across the flow of people over to the Giraffe shop. Between the shop and Aladdins Enchanted Passage you should see an opening. This is the next part of the hidden walkway. It looks like just a cave but when you walk though you will see the path continuing. This path brings you to Frontierland entrance. Again you need to go across the flow of people and on the other side of the entrance you will again see an opening. Again just go through this opening and the path continues. You go through the trees and pass toliets and then suddenly you are at the top of Liberty Arcade.
I hope this makes sense 
I'm still confused, can someone video it?
It is perhaps easier to find from the other side.
From the Liberty Arcade, stay on the left following the borders, and you'll see a covered path running towards Adventureland, that's the one you need. It's not marked in any way.
