This paper provides information sources and ideas for challenge and adventure activities. Main information sources are listed: libraries, ERIC, and several publishers and programs. Some useful publications are described that provide activities and ideas related to outdoor education, environmental issues, games, special populations, educational theory and practice, corporate experiential learning, facilitation, and adventure. Specific annual workshops in outdoor recreation and leadership are listed, as well as adventure organizations that offer training opportunities. Four sets of group activities for challenge and adventure programs are described: the spider's web, 2B or Knot 2B (group problem solving with ropes and knots), raccoon circles (group challenges using 1-inch tubular climbing webbing), and the lycra tube (group activities using five yards of lycra sewn into a tube).
