Hello - my parents are planning a trip to America for early next year. They will be travelling around the country for a month and want to take in the most famous sites. They really want to see the Grand Canyon but can't really work out how to get there. What is the nearest airport to the Grand Canyon, or are there no airports near to it? I know Las Vegas is fairly close but it looks like it is still a 4 hour drive. Any advise? Is the Grand Canyon on the way between two places, ie could they drive there on the way to something else?
