I know of about a bazillion places that exactly fit that description. Unfortunately, none are near LA or MS.
Now I know of a nice river you can hike into and base camp in AL, with lots of waterfalls if it has been raining at all.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
