Ala. Code § 35-15-20
It is hereby declared that there is a need for outdoor recreational areas in this state which are open for public use and enjoyment; that the use and maintenance of these areas will provide beauty and openness for the benefit of the public and also assist in preserving the health, safety, and welfare of the population; that it is in the public interest to encourage owners of land to make such areas available to the public for non-commercial recreational purposes by limiting such owners' liability towards persons entering thereon for such purposes; that such limitation on liability would encourage owners of land to allow non-commercial public recreational use of land which would not otherwise be open to the public, thereby reducing state expenditures needed to provide such areas.
