There is a steep nontechnical ascent here near the falls. If you hit this trail heading southwest you will have generally steeper uphills and more rolling descents.

After transitioning from the bike path (if you choose to do the initial section of Boulder Canyon Drive on it) the road steadily steepens as you climb up toward Nederland. Please watch out for rocks in the road, cars, and wildlife. Although this is a poplar cycling route, there are lots of cars and frequently no shoulder so be aware of your surroundings when climbing or descending.

This section of the popular Lefthand Canyon is a long, but scenic climb with increasingly good views of the often-snowcapped Indian Peaks the closer you get to Ward. Ward is a tiny mountain town just off the Peak to Peak highway with a cyclist-friendly general store. This section is also super, super fun to fly down, but be aware deer in the road and cars.
