Falls Loop Trail is one of the most comprehensive, well-maintained, and shortest trails in Shasta County. The trailhead doubles as an overlook and starts only a couple hundred feet from the parking lot. As you start your 1-mile run, you'll cross over a sweet footbridge that takes you over Burney Creek (the water here feeds into the falls) and eventually down into the valley. It's pretty self-explanatory, given that there's only one way to go, but you'll notice signposts marking the Pacific Crest Trail that sits only a few hundred feet away.
As you make your way down, remember that the loop will take you in a clockwise direction back up to the trailhead. Notice the drastic drop in temperature (especially in the summer) as you get closer to the base. Parts of the trail are shaded, thanks to the covering provided by the trees. Once there, you'll stand in wonder of the majestic 129 foot Burney Falls
with many vantage points.
Finishing the loop requires you to run back up with an elevation gain of about 200 feet. There are a couple switchbacks, each featuring a functioning water fountain to cool you off.
