Cua Dai Beach: Erosion, Recovery, and Visiting Hoi An’s Coast

Cua Dai Beach erosion changed what should have been a simple trip to the sea near Hoi An. Vivi and I found sandbags, excavators, and coastal protection work alongside the remaining beach. It was hard to look at the shoreline without wondering how much of it would survive. Since then, restoration has returned sand to parts of the coast, while further erosion and protective works have kept the story moving.

Should you visit Cua Dai Beach? I would include it as a flexible stop from Hoi An. For a vacation built around swimming and a wide sandy beach, check the exact stretch before booking. A hotel with a sea view and a hotel with usable beach access are two different promises.

Cua Dai Beach Today: Recovery and Ongoing Protection

Parts of Cua Dai have been restored, and that matters when reading older accounts such as ours. In April 2025, local reporting on the revived beachfront documented returning sand and reopened businesses along a 2.3-kilometer stretch between Victoria Hoi An and Thinh My. Our photographs of damaged sections should not be used to describe the whole coastline today.

The recovery has not removed the need for further intervention. Contractor Dat Phuong recorded the launch of another coastal protection project in March 2025, with submerged breakwaters and beach nourishment among the planned measures. Separately, Vietnam News Agency reporting on September 30, 2026 described emergency works after the 2025 storm season, including a 1.95-kilometer embankment across three sections of Hoi An’s coast. Remaining work behind that embankment was targeted for mid-October 2026. A target date does not confirm completion or usable beach access beside a particular hotel.

For travelers, the useful question is where the sand, access, and construction stand along the section they intend to use. Ask your accommodation for recent photographs of its actual beachfront and whether you can walk directly onto the sand. A general photograph of Cua Dai tells you very little about a frontage farther along the shore.

Why Is Cua Dai Beach Affected by Erosion?

Cua Dai Beach erosion has several interacting causes: changes at the Thu Bon river mouth, reduced sediment reaching the coast, waves, and human intervention along the rivers and shoreline. It is not a problem that began with one storm in 2014. Research on the inlet and neighboring beach traces serious erosion on the northern side back to 1995 and identifies river-channel movement as an important part of the process.

A beach needs a continuing supply of sand. If waves carry material away faster than it is replaced, the shoreline retreats. A 2015 study of Cua Dai’s erosion mechanism identified reduced river sediment linked to sand extraction as a likely contributor and noted the influence of hotels and embankments on the surrounding coast. Resort development belongs in the discussion, alongside what happens upstream and at the estuary.

Project documentation published through AFD’s procurement platform also points to sediment shortages associated with hydropower structures on the Thu Bon and Vu Gia river systems. Storms can then remove large amounts of beach in a short period. Sea-level rise adds pressure to an already vulnerable coast. Blaming climate change alone misses the local interventions; ruling it out altogether is equally unhelpful.

What We Found on the Beach

Our visit was dominated by the visible effort to protect the coast. Excavators and shore defenses appeared in photographs that I had expected to fill with sand and sea. There were still people enjoying the beach, and some stretches remained appealing. The construction made the damage difficult to ignore.

We also found a quieter scene than we had expected, with restaurants trying to attract the visitors who remained. Those observations belong to our trip. They are not a reliable guide to current crowds, restaurant prices, or which businesses are open. What stayed with me was the uneasy relationship between a beach sold as a holiday escape and the work needed to keep it there.

Can You Swim at Cua Dai Beach?

Swimming decisions need to be made for the particular beach section and conditions that day. Vivi and I did not swim at Cua Dai. We were concerned about the water, and we saw other people swimming, mainly locals. We did not test water quality, so our decision cannot establish that the beach was polluted or that it is unsafe today.

Before entering, check local warnings and ask whether the area is designated for swimming. Stay clear of construction, shore defenses, and the river mouth, and do not enter in rough conditions or when access is closed. A restored strip of sand is not, by itself, evidence that the water beside it is suitable for swimming. If nobody can give a clear answer about the conditions, I would keep the visit to a walk.

Cua Dai Beach’s Future: More Than a Construction Project

Cua Dai’s future depends on managing the wider coastal system as well as protecting individual sections. Breakwaters and added sand can help restore a beach; continued sediment shortages and exposure to storms remain part of the problem. The work affects homes, businesses, and public access, as well as resort gardens.

There have also been efforts beyond engineering. The International Climate Initiative records a community project using green corridors and parks at Cua Dai, running from July 2023 to June 2025. It included planting, local participation, and adaptation measures. That does not prove the coastline has been secured, though it recognizes that coastal protection involves the landscape and the people living in it.

I still find it difficult to separate a resort holiday from the condition of the shore outside. The people earning their living here have far more at stake than an interrupted beach day. For me, the value of these photographs is that they keep that wider setting in view.

Conclusion

Hoi An is worth visiting, and I would still make room for a look at Cua Dai. Combine it with time in town, perhaps including the fittings and fabric choices we describe in our Hoi An tailor experience, without making a perfect beach day the condition of enjoying the trip. If sand and swimming are your priority, compare the current frontage at Cua Dai with alternatives such as An Bang and check both locally.

What I remember most is the machinery beside the sea. It changed the way I photographed the beach and the way I thought about the holiday landscape around it. The restored sections are encouraging. They also make it worth following what happens next, beyond the point when the beach looks good in a photograph.
