How to locate the castle in Enchanted

You have to climb across the water by the pole in the air that starts on the platform that the blue things appear. You need a running jump to get on it.
Once over the other side you have to move across the narrow ledge to open the trap door this seems to unlock the water barriers. When you go down the stairs you have to fight the water troll. It is easier to use Giselle as the bait to get it over the drain, just leave the rat in the middle. Once the troll is defeated climb the pole by the car and you are at the castle.

Can someone please help me find the castle in the enchanted game. Right now on my top screen it saying it seems nobody knows the way back to the castle. You'll just have to keep on looking. I found the magic light but I'm back on the street. Can someone please help me.
