Outward Bound provides an opportunity for former AmeriCorps and VISTA members to use their education awards on something different (other than student loans and standard college costs).
This nonprofit org provides an array of wilderness-based courses ranging from canoeing to backpacking to mountaineering and others, and the courses are offered in locations across the country. In addition to accepting the education award, scholarships are available. The Outward Bound website also includes a state-by-state set of job listings.
