It is iconic and you have to go no matter what. There are 2 consecutive cable cars but you can stop and relax in the first one. We were short on time to see the sunset and the lines were huge even with advance purchase, we had to give up and return the next day with plenty of time. We buy direct access. Much more expensive but you don't queue at any of the gondolas, both going and returning. Although if you go 2 hours in advance of sunset there are no lines, as the time approaches the intermediate gondola collapses, so if you don't mind paying more I recommend direct access. The views at sunset are spectacular, with Christ the Redeemer next to it, and you see Rio 360º with which you see how huge and beautiful the city, its bays and its beaches are. Above all, choose a day with guaranteed sun, if it is cloudy you will not see anything. That is why the stay in Rio has to be 4-5 days to guarantee that someone will have full sun. A beauty.
