Teatro Colón guided tour
The Colón is one of the great opera houses of the world and there is no free way to see the inside. The guided tour takes you into the horseshoe auditorium, the Golden Hall and the foyer. Book it on the theatre site a few days ahead, since the English-language slots sell out first.
Everything above is free. This is the only paid pick on the page, chosen because no free option replaces it.
