The Palouse to Cascades State Park Trail is a long gravel route across Washington, great for bikepacking or long rides. The Snoqualmie Tunnel is a must—dark, damp, and fun (bring lights). Expect wind and remote stretches, so pack water and gear. Riding over trestles and through changing landscapes keeps things interesting the whole way.

The Hall Creek Trestle is a historic steel and timber railway bridge built in 1912. It was once the old Milwaukee Road until, in 1988, a storm washed away a central 171-foot section of the bridge. In the 1990s, Washington State Parks restored the trestle, reconnecting the east and west segments of the former rail line, which is now part of the Palouse to Cascades (Iron Horse) Trail. The views down into Hall Creek Valley are genuinely stunning and worth the ride!

The Northern Pacific Railway Steam Rotary Snowplow No. 10 is a rare steam-driven snowplow constructed in 1907 by the American Locomotive Company in Schenectady, New York. This snowplow efficiently cleared the snow on Stampede Pass from 1907 until 1964. Although its original wooden body was replaced with steel in the 1950s, the cutting blades and rotating scoops that effectively flung the snow clear of the tracks are still the original components.
