Taean Sinduri Coastal Sand Dune is the largest coastal sand dune in the country and a natural monument, stretching beside the sea in Taean. It is a nature reserve where sand dunes and coastal vegetation can be seen, with a walking path running along the sea. The path is laid out with wooden decks, making it easy to walk, and the pine forest side offers shade and cool wind. Grass covers much of the dune, so desert-like sand dunes are not easy to see.
