What is Chinook Pass?

What is Chinook Pass?

Headed to Mount Rainier from the east? Odds are you’ll make your way along Washington’s State Route 410 to get there. Chinook Pass, at an elevation of 5430 feet (1656 m.) marks the east entrance to Mount Rainier National Park along SR-410.

Wintery conditions and severe avalanche risk keep Chinook Pass closed from November to May. When it is open, however, the road up and over Chinook Pass is considered one of the most beautiful scenic drives in all the United States.

Dubbed the Chinook Scenic Byway, the road carries Washington tourists from Sumner, Washington, through the Cascade Mountains to Naches, Washington. Commercial vehicles aren’t allowed to commute through Mount Rainier National Park, reducing traffic and making it pleasant for summer travelers to visit the area.
