There is a sandy beach with an old shipwreck, which can be reached by a sandy road accessible only by 4x4 vehicles. It is recommended to lower your tire pressure to avoid getting stuck. While the beach itself is visually appealing, it is unfortunately quite dirty with trash scattered about. However, it is a peaceful and quiet location.
Without all-wheel drive, I can make it to the dune right before the beach in a 6-meter Sprinter van. However, the dune itself is heavily covered in sand. There is a lot of sea debris, but otherwise, it is a beautiful and secluded spot of land.
You cannot ascend the sand dune using a 4x4 van; it appears feasible only with a 4x4 car.
