Washington trails · Rattlesnake
A 10.3-mile network in Washington, with 2,425 ft of climbing. Reaches Rattlesnake Mountain and other summit/viewpoint destinations. Managed by WA Department of Natural Resources.
The climbing leans toward the first third: 45% of the ascent falls between mile 0.0 and mile 3.4. It gives back about 1,570 ft along the way, so it rolls rather than climbing steadily.
