It honestly felt very safe going through the favela. Uber drops you to the bottom of the favela, then there were police cas and the moto-taxi people all in an area at the bottom. There was no-one other than tourists doing the hike on the trail, the only part of concern would be when you arrive back at the top of the favela waiting for a moto-taxi to arrive. There is a little guy with a shop there as a local, so you wouldn't be completely alone, although you may have to wait 10mins or so. I'm quite risk averse, and I did it without the tour guide.

I think may be to risky to go there in night time. you shouldn t go mate!

As vãs continuam circulando entre o leblon e o vidigal. Sugiro que verifique se há indices de violência antes de fazer a trilha do morro dois irmãos. Para chegar ate "o pé" de onde começa a trilha você pode ir de moto taxi ou combi. Evite fazer a trilha se a semana foi chovosa pois lá tem bastante terra que irá dificultar sua subida. O morro dois irmãos tem umas das vistas mais bonitas do Rio de janeiro

Hasta la entrada del parque, por la favela que está en el morro, pero llegado a ese punto hay que seguir a pie sí o sí.

Yes, go there my friend!

Pode ir de carro.

Ola amigo q tal, tranquilo? The sun is rising like 6:25h next week so from copacabana plus the way up, with a good lantern and some snacks and water, you can at 4h from copa, 20 min to vidigal, get a mototaxi to the top of the favela, and then starts the hike, less then an hour to do it, and really worth it. Don't forget the jacket, Dale, bien venido!
