Many interpretive nature trails have been established for the visually impaired in recent years. The objectives of the investigation were to (a) identify what has been done in the past in the way of nature trail design for the visually impaired, (b) compare this with what professional workers for the visually impaired consider important in the design of the facilities, and (c) to provide guidelines for the design of future trails for the visually impaired. It was determined that the "typical" nature center was over five miles from the nearest urban center, not on public transportation lines, and provided a single special trail for the visually impaired with guide ropes and braille signs. As a result of the literature search, the informal interviews with visually impaired students, and the survey of Orientation and Mobility Instructors, the following suggestions are made for the design of future nature trails: (1) No special trails should be established, as these tend to isolate the visually impaired from the rest of the visitors; (2) all trails should be clearly differentiated from the surrounding environment so that the visually imparied can use residual sight or proper mobility techniques for travel; ropes are unnecessary and often vandalized; (3) special pavement is not needed; (4) railings should be provided at hazardous areas; and (5) interpretation should be offered through the use of portable cassette tape players, and booklets for the hard of hearing.
