WA-129 runs 43 miles south from Clarkston through the Snake River canyon and up Rattlesnake Grade — nine switchbacks climbing 840 feet in under 4 miles from the canyon floor to the Asotin County plateau — before continuing to the Oregon state line at Anatone where it becomes OR-3. The American Motorcyclist Association has named this corridor one of the top 15 motorcycle rides in America. The route delivers canyon walls, wheat-field ridges, and the Joseph Canyon Overlook with views into the historic Nez Perce winter homelands. Very low traffic throughout.

Anacortes Oyster Run
Washington
The Anacortes Oyster Run is the largest motorcycle run in the Pacific Northwest, held annually on the fourth Sunday in September in downtown Anacortes. The 43rd annual event is scheduled for September 27, 2026. The event is free, unstructured — no start point, no required route, no registration — and draws riders from across the region to fill Anacortes's waterfront downtown with bikes, vendors, and live music. The Seattle Cossacks Motorcycle Drill Team performs at 11am and 1pm, and street vendors operate from 9am to 5pm. The event has run continuously since the early 1980s.

Cayuse Pass (WA-123)
Washington
WA-123 is a 20-mile two-lane road running north through the east side of Mount Rainier National Park from its junction with US-12 near Packwood to Cayuse Pass (4,675 ft) where it meets WA-410. The road follows the Ohanapecosh River corridor through old-growth forest before ascending to the Cascade crest alongside Stevens Canyon Road's dramatic switchbacks. Combined with WA-410, it forms the classic Rainier loop — riders can string Chinook Pass (WA-410) and White Pass (US-12) into a single circuit. Seasonal closure (November through late May) matches WA-410.

Chinook Pass (WA-410)
Washington
WA-410 climbs from the Naches River valley west through the Cascades to Chinook Pass at 5,430 feet on the eastern boundary of Mount Rainier National Park, then descends into Enumclaw. The 95-mile run offers consistent two-lane curves through old-growth forest, subalpine meadows, and river canyon — peaking at Tipsoo Lake with a direct view of Mount Rainier across the water. The road is designated an All-American Road as part of the Chinook Pass Scenic Byway. Seasonal closure applies: the summit section is typically closed November through late May due to snow.
