The track reaches a height of as it passes around the peak of Mount Bellamy. The terrain rises and falls with regularity, up to up and down over the full length of the track. This markedly increases the distance to be traversed, although there are several flat areas, particularly around Myola. The vegetation is largely dense jungle. The climate is mostly hot and humid with high rainfall, although the higher parts are cold, particularly at night. The higher elevations are frequently above cloud level, resulting in fog.
