There are instructions all over the forum, but the basic concept for Chrysolia Forest is a 3x4 set of rooms with "revolving doors." I say revolving doors because basically you enter one room and an entrance opens and closes. There is one path that is kind of hard to see, but basically just keep moving forward from room to room. Trees will open one path and close another so you loop around a couple of time in the forest but eventually you get to an exit.
