What a fun little boat trip! This portion can only be rafted when the flow is just right. Too little water and you are dragging the raft over the shallow spots, but too much water can be too dangerous. During the sweet spot, there can be quite a few boats on the water, but it is worth it. Our day included rafting through rock faces, watching the birds fish and swim, testing your skill and strength in avoiding bouncing off the rocks and the icy cold, nearly unbearable water. This little spot is very accessible to Great Falls. Plan about 90 minutes travel to and from and 2-3 hours in the water.
