W du Niger National Park is a UNESCO World Heritage site located where Niger, Benin, and Burkina Faso meet. Renowned for its rich biodiversity, the park is accessible from Falmey, with the best travel period being the dry season from November to April when wildlife spotting is more frequent. Travelers can visit the park independently or join guided tours, which are highly recommended for a more informative experience and include game drives and bird-watching tours. The entrance fee is reasonable, but costs can vary depending on whether you opt for additional guided services. Typically, a visit can take a full day to several days if you choose to explore extensively. Ensure you have a 4x4 vehicle for the rough terrain, and accommodations can be arranged nearby or within the park depending on the type of experience you seek. Additionally, it's advisable to book in advance, especially during peak tourist seasons.
