River Gambia National Park, also known as Baboon Islands National Reserve, is a protected area encompassing five islands that serve as a sanctuary for diverse wildlife, including chimpanzees, red colobus monkeys, and various bird species. Accessibility to the islands is primarily by boat, and it is highly recommended to visit with a guided tour to maximize wildlife spotting opportunities and ensure safety. Solo visits are generally not advised due to the nature of the reserve. The dry season (November to May) is typically the best time to visit, offering more favorable weather conditions and increased chances of wildlife sightings. Costs can vary depending on the tour operator and duration of the visit, but expect to pay for park entrance fees, boat transportation, and guide services. A typical visit can range from a day trip to multiple days, depending on your interests and chosen itinerary. Be sure to bring appropriate clothing, insect repellent, and sun protection.
