CERTIFICATION AND TRAINING

All of our guides undergo training through the AMGA and receive annual CPD. A majority of our guides hold AMGA Guide Certifications, which indicates they have the highest level of training within that discipline. This commitment to their own high-level technical abilities and professionalism through certifications ensures that you work with the best in the industry, regarding security, industry best practices, and movement ability. We know that’s not everything to look for in a guide, but it is a really great start…
