This section of the Skykomish is one of the most famous and popular rafting trips in Washington. One of the major draws is the spectacular scenery, including not only the clear, greenish water and giant granite boulders of the river, but also the towering and snow-capped mountains like Mt Index that loom above it. The run starts on the South Fork but quickly enters the main channel and heads into the first rapid, Class III Cable Drop. Several more small rapids pass before the main event, called Boulder Drop, which happens in three sections. The second section, called Picket Fence, offers the greatest choice in lines, as you must pick between 6 passages in between large boulders. Mercy Chute, on the far right, is often selected. Boulder Drop can be portaged on the right. Many people rest at 2.25 miles near Lunch Hole. The trip is rounded out with several more Class III rapids. The hazard level varies significantly with the water level, up to potential Class V at flows above 5,000 cfs.
