Boulder Creek Falls is an interesting roadside waterfall off Hwy 190 between Springville and Ponderosa. It cascades besides the road before going underneath the road as the falls continues its descent into the steep canyon below, eventually joining the Middle Fork Tule River. You can pull over at one of the shoulders nearby the falls so you can view the falls without blocking traffic. Just be sure to stay clear of the road as vehicles can travel quite fast on this highway.
