In this research, the recreational value of the Radio-darya coast of the Chalous coastline was estimated, alongside the measure of visitors' willingness-to-pay (WTP), by using a contingent valuation (CV) method and dichotomous choice (DC) questionnaire. WTP was measured by using a Logit model which parameters were estimated based on the Maximum Likelihood (ML) Model for the year 2009. The results show that 65 percent of investigated individuals will pay for recreational usage of the aforementioned coast. The average WTP is 1169 Rials (about 1 USD) for each visit. Recreational monthly value of this coastal region is more than 37.75 million Rials (about 3230 USD); to be precise, the total annual recreational value of this area is estimated to be about 453 million Rials. Furthermore, the variables of "offer" and "visitors' income" are statistically significant at the level of 1%; so, these two variables are considered as the most important factors affecting visitors' WTP.The next factor influencing their WTP, from the point of view of visitors, is the quality of the coast (coastal neatness and water limpidity) which is significant at the 1% statistical level. Level of education is the next effective factor with significance at the 10% level. Moreover, distance between the coast and place of residence is the next factor affecting WTP negatively at the 10% level.
