5 major trails of Odaesan National Park were selected to investigate the use impacts on environmental deterioration of trail accreding to the different amunt of use. The entire width, bare width, maximum depth and slope of trail as the trail comdition surveyed at the total of 120 points were significantly greater on the more heavily-used trail. Major deterioration types of trail were root-exposure, rock-exposure, deepening and divergence in order of frquency and trail conditions of deteriorated points were significantly different from those of non-deteriorated points. The damaged area more severe than Class 4 on trail reached about 379m$^{2}$/km in total, and especcially about 1,196m$^{2}$/km in the section between Chodmyolbogung and Pirobong of Sangwonsa trail. The dominant trees of trail edge vegetation could be Quercus mongolica in upper layer, but in lower layer Rhododecdron schilipenbachii for slope and Actinidia arguta for ridge. Coverage and number of individuals of lower vegetation in trail edge were the lowest on the Sangwonsa trail of the largest use amount, and each trail was dissimilar in species composition of lower layer of edge vegetation.
