Survivors of sexual abuse are likely to be among the participants of many adventure and experiential programs. This paper aims to increase outdoor leaders' understanding of the possible reactions of survivors to adventure experiences and related group interactions. Long-term effects of sexual violence are pervasive and may be triggered by the unusual experiences in adventure programs. These effects include flashbacks of emotions or physical sensations of abuse; dissociation of mind, body, and spirit; feelings of loss of control; anger, turned inward or outward; shame; lack of trust; and difficulties with personal boundaries. Participants may be limited in their ability to withdraw from activities. Corporate and school groups may require 100 percent participation. Adolescent girls, in particular, may be reluctant to speak up about their discomfort, and instead, may try to influence the group to withdraw. Challenge is something of a "sacred cow" in experiential education; some rethinking should be done about providing true "challenge by choice" and about the nature of success in challenge activities. Practical suggestions are offered in relation to the extent of touching during initiatives, the importance of cleanliness to survivors, feelings of lack of control due to environmental elements such as weather or insects, nudity, and sleeping arrangements.
