Pack only essentials: a sturdy tarp, a small fire starter kit, a reusable water bottle, a multi‑tool, and a light, quick‑dry shirt. Cut your shoes to slip into sand quickly, keep a small knife for cutting rope or wood, and store a tiny first‑aid patch in a zip‑lock bag. Use a stick as a spear or walking stick, and always mark your route with a bright flag or spray. That’s all you need to stay sharp and ready without the bulk.
