PGS Guides

Our guides are highly qualified and will be involved in an internationally accredited certification program. The UIAGM (Union Internationale des Associations de Guides de Montagnes) and the AMGA (American Mountain Guides Association) run internationally recognized certification programs for aspiring mountain guides.

It requires three to four years of intense training, testing, and supervised guiding to become fully certified. For more information about UIAGM and AMGA qualifications, check the AMGA home page at amga.com
