The final sign is the exit only sign as seen on the bridge over the waterway. This little bridge has been removed during the many rehabs of the area and now you just walk out on the veranda and down some steps and back into Adventureland.
Before you leave though, make sure to deposit your trash in the appropriately themed Trash can. The bullet shaped trash cans have now been replaced with the larger square shaped trashcans. The interior holders are a standard size although Disneyland still themes the cans.
