How does the traveler describe the road he finally choses in The Road Not Taken?

The traveler describes the road he takes as the one "less traveled by." He also describes it as "grassy" and says that it "wanted wear," meaning that it is not worn out by people using it. The fact that it is "grassy" also means it is not well traveled, because if it were--if many feet and horses' hooves had trod on it--the grass would be stamped down and killed. 

He says that the road he takes, like the road he doesn't, was covered with "leaves no step had trodden black." Like the grass, the untrampled leaves indicate that few people have gone down this particular road. 

We also are told this road is in a woods, meaning the narrator is going down a path that is shady and a bit mysterious: he can't be quite sure what is to come.
