Cửa Đại Beach sits at the confluence of three rivers - the Trường Giang, Đế Võng, and Thu Bồn - about 4-5km east of Hội An Ancient Town and 30km south of Đà Nẵng, where fresh water meets the East Sea. It's the most accessible beach from Hội An - flat cycling distance from the Ancient Town on a road through rice paddies and the coastal village of Cửa Đại - and has long served as the primary beach day option for visitors based in Hội An, with some local accounts describing it as the region's most celebrated beach going back to the Champa era. Rows of coconut trees line parts of the shore, providing natural shade where the beach is intact.
Beach Erosion and Early Fixes
It's important to know the beach's recent history, though: Cửa Đại was once ranked among Asia's most beautiful beaches, but severe erosion set in from 2014 onward, worsened by upstream dam construction affecting sediment flows, washing away large sections of sand and, at its worst around 2020, leaving the beachfront devastated. Early efforts to fight the erosion were piecemeal - sea walls and sandbags patched wherever erosion struck, costing hundreds of billions of VND without solving the underlying problem. A 2016 study funded by the French Development Agency (AFD) led to a more systematic plan: a submerged offshore breakwater combined with large-scale sand pumping.
Breakwater Project Progress
The first phase (2020-2024, three projects totalling 550 billion VND) built over 2.3km of breakwater - set half a metre below sea level, running about 250m offshore, roughly 4.5m tall with a 12m base and 1.5m crest, built from large stone blocks (700-1,200kg each) faced with massive 5-tonne concrete blocks - then pumped in over 100,000m³ of dredged sand to rebuild the beach nearest An Bàng. Locals describe the result honestly: not quite as beautiful as before the erosion, but a genuine improvement on the devastation of 2020.
Current Status
A much larger, €42 million follow-on project began in March 2025, funded by AFD loans, EU grants, and local government, to extend that same approach - offshore breakwater plus sand nourishment - along the rest of the coastline. As of August 2026, this work is still ongoing, with completion now expected by the end of 2026 - so depending on exactly when you're reading this and which stretch of beach you're looking at, parts of Cửa Đại may still be an active construction zone, recently finished, or fully restored. It's genuinely worth checking current status locally before building a beach day around it specifically.
