See Sugarloaf Mountain from the air — the granite at the mouth of Guanabara Bay, with Urca and Copacabana Fort in the same stretch.
Only the 25- and 40-minute closed-door flights include Sugarloaf, Urca, and Copacabana Fort. Doors-off options on this tour do not list Sugarloaf. You see the mountain from the air rather than flying over the cable-car summit.
Book a 25- or 40-minute closed-door helicopter tour to see Sugarloaf from the air.
