Industrial Tourism is the alliance of the Park Service, road builders, concessionaires, and automobile interests that treats national parks as products to be made accessible to cars. Success is measured in visitor counts, so every new paved road brings more traffic, which justifies the next road. The result is that visitors pass through the scenery at speed and never actually encounter the land.
Abbey makes three proposals. Ban private automobiles from national parks, build no new roads into them, and turn rangers from traffic managers into guides who lead people on foot and horseback. The premise is that access is not the same as experience: effort and slowness are what let the land be perceived, so making travel easier destroys what the park is supposed to offer.
Abbey tries to meet juniper, sandstone, and sky as bare facts, not as symbols of God, metaphors for human feeling, or scientific categories. He compares this to switching off his flashlight so his eyes can adjust to the real night. Removing the layer of human interpretation is what makes close physical description possible, and it is where the book's writing on rock and plants gets its force.
Abbey and a friend float down Glen Canyon on the Colorado River shortly before the Glen Canyon Dam floods it under Lake Powell. They explore side canyons, alcoves, and ruins that he knows will soon be underwater. The trip turns into an elegy written in advance, showing how a place becomes fully visible only when its destruction is certain.
Abbey argues that wilderness is a political necessity, not a luxury for recreation. Wild, unmapped country is a place where people can escape or resist a centralized, overorganized state. It is also a standing reminder of a freedom that industrial civilization steadily closes off, so paving the last wild land shrinks human liberty as well as nature.
