In this paper, we present estimates of several specifications of demand for a singular natural area using data from surveys on visitors and non-visitors. The estimates take into account the problems of functional form, measurement of the cost and of the demand, choosing sampling scheme, and handling the sample. Considering these alternatives allows us to select a specification of demand under improved conditions and frees us from initial restrictive hypothesis. The results in terms of prediction of demand and consumer surplus estimates are quite dissimilar, stressing the importance of comparing various specifications that encompass a range of possible options.
