The Wenaha River flows through the Blue Mountains and the Wenaha-Tucannon Wilderness of Oregon. Most of the river is in a wide valley and much of it was burnt in the Grizzly Bear Complex Fire in 2015.
You start by hiking 5 miles down a pleasant trail to the river. There is a backpacking trail along the entire left side of the river with many established camps.
After hiking in you can put in on the South Fork of the Wenaha or hike downstream half a mile to it's the confluence with the North Fork of the Wenaha if you want more water. The river starts off small, swift, and brushy. There are many creeks that add water as you go making it more runnable. The trip ends at it's confluence with the Grande Ronde River at Troy.
In general the river is continuous Class II and III with the occasional wood and strainer hazard. The whitewater is fairly straightforward but the combination of it's continuous character and unknown wood in the water makes it potentially dangerous. You'll need to be a confident boater who can see and avoid these dangers.
Car shuttles can be arranged by calling the Minam Store at (541) 437-1111.
