The day after the Pedra da Gavea climb, I went to Corcovado. I was tempted to climb that as well, but I kept reading about robberies on the trail and in the end I decided just to get the bus up. Tiredness from the day before may also have been a factor.
So I got the bus up, getting charged the high season fare even though I was the only passenger, because supposedly it was the school holidays. And it was pretty crowded up the top. But as the sun set and the views got better and better, it got quieter and more peaceful.
