Washington Cascade Loop & Whidbey Island
Head east from Seattle through a Bavarian town and the North Cascades, looping back via the Whidbey Island coast
The standard route along the official scenic byway, taking in small towns, orchards, lakes, glacial passes, and islands. With daily drives of two to three hours, the pace is relaxed; a clockwise direction is recommended. The North Cascades Highway is closed in winter, and in 2026 it did not open until mid-June due to water damage and landslides, so verify before spring travel. Perfect for summer and autumn road trips and those who love short hikes.
WA-20 is closed from around November to April or May of the following year. Early October is best for golden larches.
