For this long and difficult route, bring plenty of water, especially during warmer months, as there are no water sources directly on the trails. Sturdy hiking shoes are essential for navigating loose sand and varied terrain. Sun protection (hat, sunscreen) is crucial for exposed dune sections. A map or GPS device is recommended, and consider trekking poles for stability on steep sandy climbs.
