A History of
Leading the way...

Acadia Mountain Guides Climbing School is the preeminent leader in climbing instruction and guiding in Acadia and across Maine. We specialize in designing customized experiences or training for you, your family or your group.

Directed by internationally recognized IFMGA guide Jon Tierney who has been climbing in Acadia since 1982. Jon has over 30 years of local and worldwide experience. The IFMGA requires full AMGA certification as a rock, alpine and ski mountaineering guide.

All AMGCS instructors are certified by either the AMGA or the PCIA and all guides have been trained or certified by the AMGA.

• Since 1994 •
AMGCS is one of 30 AMGA accredited programs in the US and was one of the earliest to achieve accreditation.

AMGCS is the only climbing school in Maine to remain continuously accredited by the AMGA for eighteen years - several years longer than any other local service. We have had one or more full time AMGA certified rock instructors or rock guides on staff each year since 1994 - sixteen years more than any other local school.

• Since 2007 •
AMGCS has the distinction of also being accredited to the highest standards of the Professional Climbing Instructors Association. The PCIA requires all staff to be individually trained and certified.
