Map & visitor guide

Know Before You Go

The Palouse to Cascades State Park Trail is not a fully improved, continuous "cross state" trail. Several sections are closed to public access due to safety concerns, active rail use and private property. Exploring the PTCT requires informed planning and preparedness and, in the eastern section, pre-registration. Please familiarize yourself with the trail before visiting.

Click here to visit the Palouse to Cascades State Park Trail Visitor Information Map for more information about surface condition, trail ownership gaps and closed bridges.

We are actively working to improve and adapt the PTCT for recreational use, which makes it a dynamic state park with ongoing projects that that could temporarily impact access.

Section Highlights and Attractions

This trail features some of Washington state’s most unique and iconic landscapes. The Palouse and Columbia Plateau – the latter featuring deep channels carved by the Missoula Floods (aka Ice Age Floods). Rock Lake (public access is closed pending renovation of several trestles and tunnels) is a prime example of the power of the Missoula Floods featuring dramatic basalt cliffs along the lake’s seven miles.

There are several train-era features along this section, including the Tekoa Trestle, a 976-foot-long trestle rising 125 feet above Hangman Creek. The Rosalia Railroad Bridge, a unique reinforced concrete archway (designed to catch the eyes of passengers on two competing rail lines and the county road) which was added to the National Register of Historic Places in 1982.
