The study would try to recognize the motive of climbers' participation, the identification of safety management and the understandings of special mountain climates by using in-depth interview, including 5 experts'. Through the expert interview, the result would be able to analyze the principles of present climbing activities, and it would also offer the making regulations of authorities. In addition, it would be viewed as pre-study for future related research. The major results would show that the reasons of first mountain activities would be "interests of wonderful landscape", "investments of Climber groups", "making friends" and "touch of nature". The reasons for the continual participation would be "personal habit", "improvement of heath" and "touch of nature". For the happened hazard, "changing climate", "accident fog" and "accident rain" would play the main roles. Because of "the changing rapidly climate" and "difficult safety controlling", the more dangerous mountain at Taiwan would be "Da-Pa", "Wu-Min", "Chuo-Wan Kan" and "Chi-Lai". In the part of safety management, the group activities have more insurance than the personal activities because of the group enforce insurance. In addition, the time spending would depend on the different climbing line. It is not suitable to join the climbing activities when the climber cannot have enough spirit and brawn. For the communication facility, the "GPS", "sell phone", and "Satellite telephone" would be viewed as better ones.
