The river flows between the Winkie Country and the mountain of the Hoppers and Horners. Some very large fish live in the Trick River and it has steep banks in most places.
The river is unique in that it changes direction every little while; sometimes it flows one way and sometimes the other. At the end of the trick part of the river is a high bank of water, like a steep hill in the river. After this it enters the Winkie Country and flows very near the castle of the Tin Woodman.
