This page is mostly dedicated to the true summit of Rattlesnake Mountain just south of North Bend and will focus little on popular Rattlesnake Ledge 2.5 miles to the south.

This is a fine hike on a well maintained, albeit busy trail through the forest with views of the Cedar River watershed, Mount Si, Mount Washington, Rattlesnake Lake and Chester Morse Lake.

If you’ve hiked to Rattlesnake Ledges and beyond from Rattlesnake Lake, this is a delightful alternative. Thanks to the handiwork of various groups in the outdoor community, hikers can now reach Rattlesnake Mountain from the west, starting from a trailhead at Snoqualmie Point.
