It is indeed in the canyon, which starts at Lee's Ferry.

No, not in the canyon or even in the Park.


It's not inside the park, but it's inside the SFRA, which is bigger than the
park (the park covers only a fraction of the canyon).

How big a fraction would that be? About 100%? (Not including certain
tribal rights.)

There's also Phantom Ranch, but it cannot accommodate fixed-wing aircraft as
far as I know.

Ever been there? I have.It can't accommodate any GA aircraft. But at
least you have finally named a place that is "down in the canyon."
