The Keystone experience amplifies the importance of the Foundation skills and builds upon experiences from Cornerstone trips through significantly elevated risk. Safety and outdoor skills are employed, as is full reliance on team members. Participants practice leadership skills, while pushing their own boundaries to achieve personal goals. Keystone is the highlight of the BOLD experience with 8 to 10 day outdoor adventure trips in North, Central and South America. To date, BOLD has led over 20 treks in 8 different countries.
