This concentration of tourism is by design. They call these areas "dead zones." The idea is to create a national park of millions of acres and concentrate all the tourism into just a few select areas and roads. You assume these areas will experience significant environmental degradation but the remaining park will be largely untouched, aside from the occasional backpacker. It makes good sense to me if the main goal is preservation.
