There are two ways to reach the falls from the trailhead, via the horse trail or along the creek. The trail along the creek is steep and rocky and should not be attempted if you aren't prepared to scramble across large rocks along the creek. The horse trail route is a slower and steadier descent, much easier on the knees. Hiking boots are recommended for both routes. The trail continues past the falls and can be used to access the Warner Valley via the Pacific Crest Trail.
The Kings Creek Falls trail leads to a large roaring waterfall draped in ferns and other green plants which thrive off the mist generated by the falls. Depending on the time of year you hike to the falls you may see Fawn Lilies or Satin-leaf Lupines in full bloom. As you get closer to the falls notice the deep bending of many of the large California Red Firs (see gallery below). Due to its elevation the Kings Creek Falls trail can be covered in 15 feet or more of snow in the winter, the immense weight of this snowpack bends the trees as they grow upwards towards the sun. As this snow melts the abundance of water in the area supports many difference species of plants and animals. The Kings Creek Trail is a great area to catch a glimpse of Lassen's various wildlife such as Clark's Nutcrackers and Mule Deer.
