Coastal and marine tourism in Korea had long been considered to be weak relative to the country`s abundant resource potential. In recent years, however, much evidence suggests that marine tourism and recreational activities have reapidly increased due mainly to the secular growth in personal disposable income. To ensure sustainable marine and coastal tourism, proper management of coastal resources and the environment is essential. It is widely recognized that marine tourism and recreational activities are highly dependent upon the marine environment. This study attempts to provide the policy options for the sutainable marine tourism development in Korea, based on the analyses of endowment in marine tourism resources and of activities of marine tourism and recreations.
