The route starts as a limited-access southerly bypass of Downtown Sumner, but becomes a surface road east of the city. Traveling eastward, the roadway serves Bonney Lake and Buckley, and crosses and eventually parallels the White River into Enumclaw and Greenwater. SR 410 enters the Mount Baker-Snoqualmie National Forest and later heads into Mount Rainier National Park, crossing the Cayuse and Chinook passes, and leaves the park southeast along the American River into Wenatchee National Forest. SR 410 leaves the national forest and travels parallel to the Naches River to end in Naches, a city located west of Yakima. The Chinook Scenic Byway begins in Enumclaw and follows the highway through the two national forests and Mount Rainier National Park to US 12 in Naches.
