A village in the US only be reached by foot or helicopter
This is interesting and I just have to share. The village is in Grand Canyon- Arizona.
Here is a description from Wikipedia
Supai has been referred to as “the most remote community” in the contiguous United States by the U.S. Department of Agriculture. It is accessible only by helicopter, on foot or by mule. Supai is 8 miles (13 km) from the nearest road and has no automobiles in the community. More info can be read on wikipedia
