The trail offers a remarkable range of terrain, transitioning from the evergreen forests of the Cascades to irrigated farmland, arid scrubland, and the rolling hills of the Palouse region. It's primarily a rail trail, meaning it has gentle grades, mostly light gravel surfaces, though some sections can have loose gravel or sand.
Yes, the trail is generally considered easy to moderate. As a rail trail, it features gentle grades, never exceeding 2.2%. While some sections can be long or have varying surfaces, its overall gentle incline makes it manageable for many hikers, including beginners looking for longer distances.
The trail is rich with features. Highlights include the 2.3-mile-long Snoqualmie Tunnel, historic railroad trestles like the Tekoa Trestle, and the recently renovated Beverly Bridge over the Columbia River. You can also see the Irrigation sluice speedway, the Teanaway River, and the historic Cascade Rail Foundation South Cle Elum Station. Other points of interest include the Yakima River Bridge and Lake Easton Tunnel.
