Using a contingent valuation method, this study estimated the value of the Seoraksan National Park. Particularly, it compared the non-market value of the national park when it had a cable car and when it had not. Data were collected from 403 visitors of the national park on May of 2009. Results showed that the benefit value of the national park could be from 45.7 to 52 billion won per year when it had a cable car in the park. However, the benefit value could be only from 2.9 through 3.6 billion won per year when there was no cable car in the park. This suggested that the benefit value of the national park could be 15 times larger when the park had a cable car. Results also indicated that the respondents considered ``appreciation of beautiful scenery`` as the major attraction of the Seoraksan National Park. The respondents also tended to think that installation of cable cars could be a new method of inducing tourists as well as preventing environmental damage of the Seoraksan National Park.
