ABOUT THIS ROUTE
This is the full-day epic: four mountain gates in one loop. From Ashford the road climbs to Paradise, where the wildflower meadows sit directly under the 14,410-foot volcano, drops to the Nisqually and Packwood, then tops Chinook Pass — riding under the enormous timber arch that marks the boundary — before the long dry run to Ellensburg for fuel. The return crosses Yakima’s hop country and climbs White Pass, twisting through Gifford Pinchot forest back to Packwood. Long, demanding, unforgettable; Chinook and the Paradise road are both seasonal.
Out of Ashford the Longmire gate road follows the Nisqually to the park entrance, then the Paradise line climbs past the Narada falls to the 5,400-foot meadow heart of the park — arrive before ten or queue behind RVs. South through the Tatoosh shadows to Packwood, then SR-123 and SR-410 climb Chinook Pass through old burns to the famous arch at the top — one of the great motorcycle photos in the state. East of the pass the road falls to the pine flats and the dry heat of Ellensburg, the loop’s halfway fuel point. South on I-82 for ten miles (the only interstate stretch) to Yakima, then west on US-12: hop fields give way to the Rimrock lake climb and the twisting White Pass descent through fir forest to Packwood. Two national parks’ worth of scenery, one fuel loop.
