My favourite spot in Rio isn’t lying on Ipanema beach or watching the world go by sitting in the Copacabana Palace terrace. Nor does it involve hiking in the Parque Nacional da Tijuca, or snaking around the islands on a boat trip in Guanabara Bay. My favourite spot is unfamiliar to the casual tourist, because it’s difficult to find. You can’t even spot it from high up in the favelas or from the statue of Christ the Redeemer. In fact I’d really have to give you directions there.
