The mangrove area of Togean Islands have been used for marine ecotourism activities. The increasing of anthropogenic activities affected to decreasing of mangrove area and mangrove tourism attractive. This research aim to assess characteristic and suitability of mangrove forest area for mangrove ecotourism uses. The data were analyzed using principal component analysis (PCA) and spatial analysis with geographic information system (GIS) approach. The result showed that the correlation value of those four parameters was relatively higher in November than in July. Those parameters were the component that forms the main axis in both month. The increasing of turbidity and decreasing of salinity in November rather than in July were correlated with rainy season. Generally, mangrove area in Togean Islands was suitable with conditional categories to mangrove ecotourism uses. Ecotourism has the most potential to meet these goals and it will be able to tackle most of the problems when GIS technology would be used as a tool to minimize the impact.
