Practical advice for the dunes
Always pack biodegradable sunscreen to protect the delicate lagoon ecosystems. The sun is intense, so wear a UV-protection rash guard and a hat with a chin strap to handle strong winds. Bring a reusable water bottle, as hydration is essential in the high heat.
Sandals or flip-flops are necessary for the trails, but walking barefoot is best once you reach the actual dunes. Keep a dry bag handy to protect your phone and camera from blowing sand.
