The answer you want is Canyon. Can·yon (the dot is placed on purpose)
the ñ has a y sound to it, you can figure this out by going to google translate and just putting in the ñ then click the little speaker. Plus, if you change the word canyon to <span>cañon then click the speaker button in google translate it sounds exactly like if you were to just say "Canyon"
Hope this helps!
Ps: If you do do google translate MAKE SURE you type you are on the spanish button, as if you are typing in spanish! </span>
