With Ecuador already closed off to climbing, it'd be a real shame if one of the greatest alpine playgrounds In the world is no longer an option.
In both areas, it seems only applicable to standard routes on the popular peaks. For Ecuador, it is mostly limited the standard routes on Illinizas, Antisana, Cotopaxi, Chimborazo, and Cayambe. If you want to climb something more difficult that most guides don't want to do (say, some of the routes on El Altar), it seems that you are given a pass.
Same with the Blanca. If you want to do the standard routes on peaks such as Huascarán, Chopicalqui, Copa, Pisoco, Alpaymayo, Artesonraju, and a few others, it seems likely to be enforced since the guides often do those peaks. If you wanted to do something remote or difficult (peaks such as Cayesh, Huanstan, Chacraraju, etc.), or an unusual route, it seems that you are given permission even if you ask for it (with proof of experience), since the guides don't climb those peaks or routes.
For both areas, it seems that the popular guided routes are really where the issues arise. Although safety is usually stated as the reason, employment of guides is probably the real motivating factor. Also, to be fair, safety wise, Peru doesn't have the resources for many rescues of climbers.
I'm old, slow and fat. Unfortunately, those are my good qualities.
