There are a few things we will do differently if we make this trip again.
- Build in an extra day at Posada Barrancas. The altitude change was really noticable, and it would have been better to have a day to acclimate. We could also have gone down into the canyon from here.
- Do at least one trip down into the canyon. You can do this via ATV, jeep donkey or horse. Batopilas and Urique two towns at the bottom that are both supposed to be quite worth visiting.
- Go right after the rainy season. Apparently there are a lot of waterfalls - many visible from the train - if you go in November or December.
