If you are trying to get to the Castle Chapel the directions are typed underneath.
In the entrance hall go up the stairs and go through the middle door to the Lift stop.Follow the ledge round and go through the door that leads to the Castle Gates.Take the path up to the right and activate the blue crystal on the left taking the platform up.Fight the heartless but becareful not to fall off.
Go up the stairs to the right and activate the orange crystal.
fight the heartless and activate the crystal that appears in the middle of the platform.Clear the blue trinity and the chest and run down the stairs to your left(you can always just jump of the ledge inbetween the stone collums if you really want, but be careful not to jump right over the barrier like i did...)and enter the...entrance...black-hole-in-the-wall...something like that.
activate the blue crystal and take the stairs to your right after getting off the platform.activate the blue crystal and kill all the heartless when you get off the platform.Activate the orange crystal to lower one side of the bridge and enter the black-hole-in-the-wall that leads to the other side of the giant stairs.Kill all the heart less and activate the orange crystal.Jump up the griant stairs And run around the corner to the Castle Chapel entrance.
