Where to swim in clean clear water in Nha Trang — best beaches and day passes?

The beach near the Do Theater (with flamingos) had remarkably clear water today — clearer than Cam Ranh, Hon Tam, the northern beach, Costa Bella, and Marina. Good visibility for snorkeling, fish easily visible.

The northern beach has a buoy-marked swimming area with a sandy bottom, no rocks, and a gentle slope into the water — comfortable for swimming.

The beach near the Oceanus hotel is calmer than the central city beach, with fewer waves.

For calm water, a gentle entry, and warm sea, Da Nang is worth considering: sun loungers with a towel start at 40,000 VND there, compared to 150,000 VND in Nha Trang.

The northern beach is currently shallow due to low tide — lots of rocks, and you need to walk about 50 meters before the water reaches your knees. Marina Beach is cleaner and less crowded since it charges an entry fee.

The beach opposite the Sapphire hotel is currently calm, the water is clean, and there is no biting plankton.

Costa Bella beach currently has murky water with an unpleasant smell — not recommended if clear water is a priority.

Amiana Resort has a day pass at 800,000 VND per adult, including towel and water. The sea there is clean and clear. Lunch for three cost around 1,200,000–1,500,000 VND.

Nha Trang's city beaches are similarly murky near the shore everywhere. Swimming about 200 meters out makes the water noticeably cleaner and clearer — bring a snorkel mask to enjoy the underwater scenery.

If warm (28°C+) and crystal-clear water is the top priority with no crowds, resort day-pass beaches like Amiana are a better choice than the public city beaches.
