I'm thinking of going to Ecuador this year and would like to try to climb Chimborazo (20,000+ ft). I've read that it is mandatory to hire a guide, so is there anyone who would like to join me on this? Apparently, the guide costs around $300 US. I've not picked a date yet, but it seems that May/June is okay. Qualified guides can be found in Quito and elsewhere. I would also like to climb a couple of the other mountains there to acclimatize, they are 18,000+ ft.
