If you are looking for a Mountain Guide try here: Asociación Argentina de Guías de Montaña (AAGM)
After 8 great years living in Bariloche I have now moved on. While I will be more than happy to try and answer any of your questions, if you are looking for up to date trail conditions I suggest you visit the National park office when you arrive in Bariloche: https://trekbariloche.com/bariloche-trekking-logistics.php#parkoffice
If you have a question, it helps if you let me know what month/season you will be coming, and what experience you have...
