Socioeconomic activities and their gross income in Isla del Coco National Park have been poorly evaluated and systematized, as well as the effects on them climate variability may have. A methodology that combines cluster analysis with a dynamic value chain was developed to identify the most important socioeconomic activities and quantify the gross income derived by the existence of Isla del Coco National Park. The possible effects of climate variability on these activities were also analyzed. A detailed literature review, consultation and interviews with researchers, entrepreneurs and tourists were conducted in order to apply the methodology. The main clusters of activities around this park are leisure and spiritual experiences, research and education, economic activities and park management. An approximation of the gross income from the activities carried out around the National Park in 2010 was calculated. The gross income generated at the national level was $5.7 million dollars and at the international level was $2.5 million dollars. The overall gross income was approximately $8.3 million dollars. But, if the natural resources being visited by tourists degrade due to the effects of climate variability  these  benefits could decrease by 30%.
