Located on the east coast of Vietnam, just five kilometers from the ancient city of Hoi An - a UNESCO World Heritage Site - Cua Dai Beach is renowned as one of the country's finest beaches, annually drawing crowds of tourists eager to bask in the magical atmosphere of a tropical paradise. The peak season in this region spans from April to September, while October marks the onset of high waves, creating ideal conditions for surfing enthusiasts and other extreme water sports aficionados. However, a significant portion of the beach has recently been ravaged by powerful ocean waves. In an effort to restore its pristine condition, special conservation measures are being implemented, including the use of sandbags, metal piles, and special bamboo structures shrouded in tarpaulin. These interventions, while necessary, have somewhat marred the natural beauty of the coastline and disrupted the serene ambiance that beachgoers seek. Typically, such sights are more common in the public and undeveloped areas of Cua Dai - near luxurious hotels and elite resorts, stone walls and breakwaters have been constructed in advance to shield the coast from erosion.
