This study derives the total economic value of La Pointe des Châteaux, the most important tourism site of Guadeloupe. The study uses the contingent valuation approach and has recourse to descriptive statistics, Turnbull estimation and probit models to obtain and assess in the first instance the use and non-use values of the site. The study reveals that the undiscounted total economic value of La Pointe des Châteaux would easily vary from 4,858,000 euros to 6,250,000 euros per year. The study also indicates that the entrance fee to the amenity would be about 6 euros per individual, per visit and the individual’s yearly contribution to a fund geared towards the preservation and improvement of the site would amount to 26 euros. These findings mean that the possibility of developing, managing and preserving the site is real. This is indeed the task that the local authority of the site should focus on, particularly in the context of sustainable development.
