Natchez Trace Parkway in How do I...? Posted July 1, 2007 Welcome to the Forums! Not all National Parks are off-limits, and no National Forests are off limits, to my knowledge. Those are our public lands and if timber companies can cut down the trees, I would hope we could put out our Tupperware containers. Check with other local cachers, and visit your Regional Forum, to see if the areas where you would like to put a cache require any sort of Permit. Some parks do. Thanks for the reply. I will check it out.
