http://www.quiltingboard.com/t-51533-1.htm For those of you going, this is an easy side trip that is REALLY worth it! You take Hwy 20 toward Salem, then turn left on Hwy 126. The lake and waterfalls are on 126. If you go further south, you'll see Hwy 242...that's the McKenzie Pass. It's a historical hwy. Two-lane, narrow, windy, but beautiful. It's closed 11 miles in right now for snow, but is supposed to be open again by end of the month (plenty of signs on it). Hwy 242 will wind you back to Sisters.
