Which beach has cleaner water in Nha Trang right now: Costabella or Bai Dai?
Based on 1 discussion with 3 participants · Last activity: 9 days ago
TL;DR
Recent reports say the sand at Costabella can look clean, but the sea often brings in floating trash and waves can be strong. Bai Dai is more exposed to the open sea, while Costabella has a stronger low tide, so water conditions should be checked on the day you go.
What the community said
A recent update from Costabella says the waves were strong on that day and a lot of trash washed in from the sea, making it a poor choice for calm swimming.

Compared with Bai Dai, Costabella sits in a more enclosed part of the coast, but even when the beach itself looks clean, currents are still dragging debris through the water. Low tide is also more noticeable at Costabella.

Sea conditions around Nha Trang can change day by day: even a supposedly perfect empty beach used on tours may have a lot of trash washed in on a bad day. It is best to confirm conditions locally before heading out.

If you are choosing between the two, Bai Dai is described as a more open-sea stretch, while Costabella is more affected by bay conditions and stronger tidal retreat. That changes both water appearance and swimming comfort.
