Gola Rainforest National Park protects the largest block of lowland rainforest remaining in Sierra Leone, extending to the Liberian border. It shelters pygmy hippopotamuses, western chimpanzees, forest elephants, and over 330 bird species, including several Upper Guinean endemic species.
Access is from Kenema, which serves as the main gateway. The Royal Society for the Protection of Birds (RSPB) and the government manage the park jointly; guided walks can be arranged through local contacts in Kenema or through the national park office. Basic accommodation exists at ranger stations inside the park. Conditions are remote and infrastructure is minimal — go with local guidance.
