This is a short drive. But filled with awe and beauty. And curves. Climbing up from Boulder, the Boulder Canyon Drive is rather steep with numerous curves. The canyon walls rise steeply on each side. And Boulder Creek is never far away from the roadway. Along the way are neat views of the Creek as it cascades down the Canyon. Part way to Nederland is Boulder Falls. You'll miss it if you've not careful. The Falls are up a rather narrow canyon. Really nice. The drive is a bit slow going. But with the views, it is well worth the curves and reduced speed.
