Planning your visit

This route is typically only accessible during the summer season, usually from June to October, as State Route 410 closes in winter due to heavy snowfall and avalanche danger. Always check road conditions before you go. While parts of the road within Mount Rainier National Park are free of commercial vehicles, traffic can still be heavy during peak season. You will find visitor areas with bathrooms and water near the summit of Chinook Pass.
