It's much longer than that. This is my favorite long distance bike trail in Washington, almost 290 miles. You can start at Rattlesnake Lake near North Bend and ride all the way to Idaho - or vice versa. Most of the trail is still on the old railroad bed (with a few detours), so it's beautiful and remote. Make sure you check the Washington State Parks website for maps, directions, advice and to register to go on the trail. It's free but mandatory if you are going east of the Columbia River. And... it's a bucket list item.

I highly recommend the Coal Mines trail as an easy access to the various mountain bike trails in the area - great system up there!

If you are starting your ride here on the Palouse to Cascades trail, take a few minutes to stop and admire the view then ride out past the watershed education center to the "Thou shalt not pass" signs (and really - do NOT trespass. The watershed folks are serious.) This is the official start of the Trail!

The Coal Miners' Memorial is a tribute to miners who lost their lives in this dangerous line of work. Below the statue are the names of the deceased listed, as well as some large-scale explosions that killed many people at once.

All told, the remade rail line known as the Palouse to Cascades Trail — also known as the Iron Horse or John Wayne trails — contains more than 100 miles (161 km) of trail from Cedar Falls to the Columbia River, all in a state park that only measures 100 feet (30 m) in width. This trail's very gentle grades make for pleasant hiking, and surprisingly beautiful views when the trees open up at magnificent trestle bridges. The trail is very popular with cyclists as well.

Rainbow Lake is a glacial lake in Olallie State Park. There is a gravel path circumnavigating it. Riders can get nice views of Rainbow Lake from the Snoqualmie Valley Trail, which runs between the trees.

There are over 20 mountain bike trails documented in Palouse To Cascades State Park, offering a range of experiences from moderate loops to more challenging climbs. The entire Palouse to Cascades State Park Trail itself stretches for 245-251 miles across Washington State.
The trails primarily follow a former railway grade, resulting in a generally level path. However, the surface often consists of loose gravel, and some sections may have loose sand. Mountain bikes with suspension and fat tires are best suited for these conditions, providing an engaging ride without extreme elevation changes.
Yes, the generally level grade of the former railway path makes many sections suitable for families. While specific 'easy' routes are available, the overall accessibility of the trail, especially in less technical sections, allows for enjoyable family rides. There are 3 easy routes and 10 moderate routes available, offering options for various skill levels.
The best time for mountain biking is typically from spring through fall. The Snoqualmie Tunnel, a major highlight, is usually closed annually from November 1st to May 1st or 2nd due to ice, which affects access to some western sections. Always check current conditions before planning your trip.
Yes, there are several loop options available. For example, the Olallie Trail loop from Wilderness Rim is a moderate 14.2-mile path, and the Olallie Trail loop from Change Peak is a 16.0-mile moderate trail. Another option is the Cedar Falls – Mine Creek Trestle Bridge loop from Wilderness Rim, a moderate 33.5 km route.
The trail passes through remote areas rich in wildlife. In the eastern sections, particularly near the U.S. Army Yakima Training Center, you might observe unique species like sage grouse. The diverse ecosystems from dense forests to arid scrubland also support a variety of other animals.
The trail offers numerous points of interest. You can bike through the historic Snoqualmie Tunnel (when open), cross impressive structures like the Hall Creek Trestle and the Palouse to Cascades State Park Trail Bridge, and enjoy views of scenic lakes such as Lake Easton State Park and Keechelus Lake, including a spot known as "The Seals".
Yes, a Discover Pass is generally required for vehicle access to state parks and lands in Washington. For detailed information on permits and fees, it's best to consult the official Washington State Parks website: parks.wa.gov.
While the trail has several state trailheads like Rattlesnake Lake, Cle Elum, Hyak, and Cedar Falls, direct public transport options specifically for mountain bikers with bikes may be limited. Planning for car access or shuttle services is often recommended. Check local transit options for specific trailhead access.
The area is highly rated by the komoot community, with an average score of 4.8 stars from over 13 reviews. Reviewers often praise the unique experience of riding along the historic railway grade, the diverse landscapes transitioning from dense forests to arid scrubland, and the impressive trestles and tunnels along the way.
Yes, while much of the main trail is relatively level, there are routes classified as 'difficult' that offer more of a challenge. For example, the Olallie Trail is a difficult 20.4-mile route with significant elevation gain through mountainous terrain, providing a more demanding experience.
Given the trail's length and varied terrain, it's advisable to bring plenty of water, snacks, a repair kit for your bike (including spare tubes), and appropriate clothing for changing weather conditions. A headlamp is essential if you plan to ride through the Snoqualmie Tunnel, even during the day, as it is dark and damp inside. Sun protection is also important, especially in the more exposed eastern sections.
