Ranked #5 in Washington, this is a wonderfully scenic bike climb in northern Washington, 90 miles southeast of Tacoma and within ten miles of Mt. Rainier at locations along the climb. 

"123/Chinook Pass West is a long and shallow ascent near Mount Rainier. Scenery is the order of the day on this hill as thick northwest woods great riders over its lower half. As you ride the trees pull back a bit and you can catch a glimpse of the big mountain in spots. Toward the top the scenery is alpine along some exposed stretches and a short tunnel. At Cayuse Pass (Route 410) turn right to continue the climb. This section is quite alpine as well and you soon come to the obvious Chinook Pass..."

Route 410 traveling through Chinook Pass is also known as the Chinook Scenic Byway, and is considered one of the most beautiful routes in the United States.  The summit of Chinook Pass is above the treeline, so there are many opportunities to stop along the roadway to see incredible scenery.  Chinook Pass also holds the east entrance to Mount Rainier National Park, so this portion of the road is closed to commercial vehicles, making this area even more popular for summer tourists.  The road is typically closed from November to May, due to its high elevation making it at risk for avalanche danger (Chinook Pass).

Turn right (east) onto Hwy 410 to Chinook Pass at mile 7.6
