What to expect on Middle Fork Trail loop from Middle Fork Trailhead

Expect a journey through an "enchanted forest" alongside the wild and scenic Middle Fork Snoqualmie River. You'll start by crossing the unusual arched Gateway Bridge, then follow a mix of singletrack and old 1930s-era railroad beds. The trail offers intermittent views of Garfield Mountain and Stegosaurus Butte, with beautiful moss-covered trees creating a rainforest-like atmosphere. While much of it maintains a gentle grade, be ready for rocky sections, creek crossings, and occasional washouts that contribute to its difficult rating, making it best for experienced joggers comfortable with varied terrain.
