Banc d'Arguin National Park, a UNESCO World Heritage site, is a coastal park known for its diverse birdlife and unique ecosystem where the Sahara Desert meets the Atlantic Ocean. Accessibility is limited, often requiring 4x4 vehicles and boats. Due to the remote location and challenging environment, guided tours are highly recommended over solo visits. Seasonal restrictions may apply, particularly during bird breeding seasons. Costs can vary significantly depending on the tour operator and duration of the visit, but expect to pay a premium for transportation and park fees. A typical visit lasts several days to fully appreciate the park's vastness and biodiversity. Be prepared for basic accommodations and limited facilities.
