Much of the research in outdoor education has focused on participant outcomes rather than the aspects of the experience that elicited those outcomes. This study explores the key elements of a 10-week expedition to Ghana with Raleigh International. Data collection involved five rounds of interviews with 14 British participants over a one-year period, using categorical aggregation to determine five principal themes critical to the experience. The findings highlight the importance of diverse groups living in isolated environments. Changing groups and moving to a new physical setting after four weeks and again at seven weeks was regarded as a challenging but necessary feature of the programme. Finally, there is little evidence linking specific programme activities with specific participant outcomes. It is more important that the experience should emphasise self-sufficient living conditions and physically demanding activities.
