So I climbing Cotopaxi in 2019 (along with a few other volcanos) so here is my research of video and resources to help learn more about the upcoming trip.
Good vidoe not much talking but a lot of quality footage of the mountain and climbing.
Not sure whwere they started from but it was a 7 hour 20 min ascent looks like they started in some sort of parking lot around 4:30 in the morning
This one is in spanish
This one has some pretty dramatic footage
