Adventurous activities can be both beneficial and perilous for health, because the circumstances differ and because of external and not always controllable factors, which may influence the outcomes. Therefore, any company, which organises adventurous activities, needs to present effective risk management and valuable safety measures in order to respond to its participants' safety and satisfaction. This study, which was performed in the Greek company «Trekking Hellas», aimed at asserting the importance of risk management for adventure tourism. The data that were collected through personal, semi - structured interviews with the company's managers and participants have shown that the particular company has made notable attempts to establish an organised and well-controlled risk management. This has been accomplished through implementing a methodical risk assessment and operating all necessary safety measures. The research, also, discussed the influence that the above might have had on the clients' motivation for participation. Finally, the data have pointed out the significance that risk management has for the success of every activity and in extent, for the success and promotion of the company.
