Chinook Pass (WA-410)

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.

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.

Diablo Lake Overlook is located at milepost 131.7 on SR-20 in North Cascades National Park. A large paved parking area with accessible vault toilets and picnic tables perches directly above the reservoir, whose water turns an otherworldly turquoise in summer due to suspended glacial flour. Below the overlook the historic Diablo Dam is visible in the distance, framed by the massive ridgelines of the North Cascades. The turquoise color is most vivid on sunny days in July, August, and September when seasonal glacial melt peaks. Riders on SR-20 pass this spot without even having to detour — the pullout is right on the highway.
