A dune is part of the coast, not a path
A dune is not an empty pile of sand to cross. It is a changing coastal system that supports plants and separates the beach from the land behind it. The municipality describes Grande Pevero as the largest dune system in Arzachena; elsewhere in the archipelago, the National Park notes dunes and boardwalks. These features are a reason to use established access points, not to create new ones.
Stay on the route even when a shortcut looks close
Reach the water through marked access points or existing boardwalks and do not cut a new path through plants. A side track can seem harmless, but repeated footsteps widen it and trample roots. If you cannot identify an official route, stop and check signs or current public information instead of guessing which sandy line is the quickest way down.
A little preparation reduces pressure
Before you set out, check where the permitted entrance is, whether parking or public transport information is current, and whether seasonal limits apply. Some beaches have separate access points or a walk; do not assume a navigation app will lead to the correct entrance. Bring water and what you need for your stay so that you are not repeatedly crossing the dune to retrieve forgotten items.
Leave sand and vegetation where they are
Do not pull up plants, collect sand or use branches to secure towels or umbrellas. Arzachena’s beach rules also prohibit resting on dunes and taking natural material such as sand, stones and shells. Avoid digging channels or holes and take all rubbish away. Small actions repeated by many visitors concentrate wear on precisely the most fragile parts of a beach.
Choose your beach using real conditions
A protected dune does not make the sea in front of it automatically safe. Wind, waves, crowds and access can change throughout the day; assess conditions on site and follow local notices. If a path is closed or the shoreline does not suit your group, choose another destination instead of going around a barrier. A planned alternative helps protect both the habitat and everyone travelling with you.
Frequently asked questions
Can I cross a dune to reach the beach faster?
Use marked entrances and existing boardwalks only. Cutting through sand and vegetation can damage roots and widen paths; if the route is unclear, check signs or official guidance. Do not climb a fence or invent another way through, even when the beach looks close.
Can I sit on a dune or take a little sand?
No. Arzachena’s rules prohibit resting on dunes and removing sand, stones and shells. Rest in permitted beach areas and leave the vegetation intact. In another location, check the local or National Park rules too: provisions can differ and protected areas may impose tighter limits.
