The Maze is to the left of Moose Jaw Falls and The Slot and to the right of Harold's Tombstone in the center of the river. This is the only good option at low flows (below 2,000 cfs).
The Maze is several hundred yards of threading through a boulder garden that doesn't have an obvious exit from the entrance. Best done the first time by following someone familiar with the route. At low flows it can be hard to find a route through. At flood it washes out and becomes moving flatwater.
