Nice loop hike out to the falls, which I have passed up before on my way to the campground. The little spur out to the falls is a nice trail. At the right time of year, at the right time of day these falls could probably be spectacular with the trees and such. Photo ops here are better later in the day rather than earlier.
There are a million ways to loop back through the Cactus Forest.
A campfire must be extinguished by drowning it with water, stirring with a shovel, and repeating that process until the campfire is cold to the touch. A campfire is still a danger if it has any trace of heat, and must not be left or abandoned. Wildfires can begin by abandoned campfires that rebuild heat on windy days and then blowing embers ignite surrounding grasses and brush.
