Rocky Run Falls is the third and final waterfall on the headwall of Rocky Run Creek. The falls can be seen from several miles away due to their height and the clear cutting which occurred in the valley downstream, however the best views are up close. Rocky Run Creek breaks over a cliff and fans out in an impressive 85 foot veil, before cascading down another 98 feet of bedrock cascades. The lower portions of the falls are lined with rather thick brush, making viewing the entire falls difficult (though most of it can be seen easily) and thanks to the long run and more gradual slope of the lower part of the falls foreshortening is significant when viewing the falls from below. When viewed from the road on the way in, the overall height of the fall is more apparent.
Rocky Run Creek drains from Lakes Laura and Lillian, neither of which have large basins. Lake Lillian will usually remain snow covered into July, providing ample flow to the creek, but once the snow has melted the volume of the creek shrinks rapidly and will be reduced to just a trickle by September.

From the Snoqualmie Pass summit, head east on I-90 to the Gold Creek exit and follow FSR #4832 signed for Gold Creek. The road passes the turnoff for Gold Creek after a mile, crosses Rocky Run Creek and then begins climbing as a gravel road. After 3.9 miles, bear left onto road #4832-136 (not usually marked). Road 136 is usually overgrown and as of July 2011 there was some nasty rutting right at the beginning that low clearance vehicles may not be able to get over (don't drive a car up it unless you don't mind seriously scratching the paint). Follow road 136 for just under 2 miles, bearing right at a fork at the halfway mark, to a large parking area at a tight switchback in the road. Find the trail at the back of the parking area and follow it up the valley through a clearcut and then into the forest, encountering Rocky Run Falls after about half of a mile.
