Saltwater marshes are beautiful, buggy, and deceptively hazardous. Proper gear transforms a miserable slog into a rewarding exploration of one of Earth's most productive ecosystems.
Chest waders (neoprene or breathable Gore-Tex) are gold standard—full leg protection, dry even if you slip into a creek. Hip waders suffice for shallow edges. Rubber boots (16"+) work for firm-ground perimeter walks. Never wear sandals or sneakers—pluff mud sucks them off; oyster shells slice them open.
Check tide tables—low tide exposes mudflats (easier walking, better birding); high tide floods creeks (kayak access). Tell someone your route and return time. Cell service often fails. Wash gear thoroughly after—salt corrodes, mud smells.
Respect the marsh: stay on established paths, don't trample Spartina grass, pack out everything. These nurseries of the sea deserve visitors who leave only footprints.
