It might seem nonsensical since the dunes look calm and peaceful, but it’s not a good idea to explore dunes. In addition to being illegal in many coastal towns, here are six other reasons why you should stay off the dunes:
1) Dunes store sand that help diminish potential shoreline erosion.
2) Dunes absorb the impact of storm surge and high waves.
3) Dunes prevent water from flooding coastal towns.
4) Dunes provide habitat and crucial nesting area for threatened and endangered species.
5) Dunes create a relaxing backdrop to any beach.
6) Dunes buffer the full force of the ocean and protect property.

Great summary. Plus it’s really hot in the swales, and plants are pricky. That beach is way more accommodating to humans.
Why would walking on them hurt the dunes seems foot traffic would not have much an impact
In my 25 years experience as an Ocean Lifeguard, I have personally witnessed the effects of foot traffic in the dunes at my home beach. Even a small amount of walking, dragging strollers, etc. keeps delicate, slow growing plants from filling in gaps in the vegetation. I can also directly confirm that where the dunes were undisturbed, seawater surge from hurricane Matthew was held back. Where people had walked on the dunes were gaps where the ocean came right through and damaged homes, streets, and other property for blocks inland. We try to educate people who don’t understand or don’t care. Please cross the dunes where the boardwalks are. It’s much safer since there are snakes, cacti, sand spurs, and debris in the sand that all can injure you.
