Isla de Mona is an extremely remote, uninhabited natural reserve known as the "Galapagos of the Caribbean," offering a pristine wilderness experience rather than typical tourism. Accessibility is highly restricted, requiring special permits from the Puerto Rico Department of Natural and Environmental Resources and an expensive, multi-hour boat charter, usually from Puerto Rico. Due to the logistical complexity, lack of facilities, and regulatory requirements, guided expeditions are essential; solo visits are practically impossible. Seasonal restrictions are significant, with hurricane season (June-November) posing considerable risks due to rough seas, making December-May the preferred but still challenging travel period. The approximate cost is very high, often thousands of dollars, due to specialized transportation and permit fees, for a typical visit duration of 3-5 days, necessitated by the extensive travel time. Visitors must be entirely self-sufficient, bringing all water, food, and camping supplies, and possess excellent physical fitness for hiking, caving, and diving in rugged terrain.
