Sun River

Sun River Professional Review and Guide

"The Sun River starts in a deep canyon, runs through prairie grasslands and finally meanders past cottonwood bottoms on its way to the Missouri. In the upper river, horizontal upthrusts create ledges of rock that cross the river and create challenging rapids.

The river is Class I and II at normal flows with occasional harder spots. Very difficult water (Class 5) for 2.5 miles immediately below Gibson Dam. Excellent canoeing stream for solid intermediate paddlers. When many streams are high and muddy with spring run-off, the Sun River may be perfect."
