It is possible to walk up to Christ!
You need quite some stamina because it takes 2.5-3 hours and the angle is around 60 degrees but it is a beautiful hike through lush Atlantic Rainforest and it is possible to sight animals like birds, butterflies, and monkeys.
When you make it all the way up Corcovado mountain, you can visit Christ for a small fee and you can also take the clogwheel train back down for relatively little money.
The tour does not happen in rainy weather or after heavy rains.
Duration: 5-6 hours
Difficulty: hard, we will walk up to 703m
