When I was in Rio me and my boyfriend went hiking the Corcovado from Parque Lage to see the Christ of Redeemer at the top.
Unfortunately, Rio is not safe everywhere and we got mugged about 1km before the end of the hike by a man with a gun and two other with knives.
Long story… there was other people hiking and everyone got robbed.
Then, they didn’t want to let us finish the hike (I guess because there was the police at the top) and told us to go back down.
We went to the police station and they told us that a lot of people get mugged on that hike.
The most important is that they didn’t hurt us but that’s so sad because the hike is amazing…
So, we took Uber (much cheaper than taxi in Rio) to go to the top to see the Christ but you can also take a train.
It might not going to happen to you but don’t take the risk.
(Finally there after that misadventure haha)
