Clearfinals:
Yep that's Grand Canyon Airport:
It gets pretty busy by day with commercial sightseeing twins in from Henderson and North Las Vegas as well as Boulder.I've also been in in one of these and we had to hold over the desert for 10 minutes on the way in as it was so busy.
There are one or two outfits at GCA itself mostly IIRC helicopters who will, for gold, take you to the bottom of the Canyon.
I agree with you, that with all the airspace restrictions self fly is not really a sensible option.
Either way have fun
