Location: Vinh Long Province (formerly Tra Vinh Province)
Reason for recommendation:
Ao Ba Om is a pond associated with the legend of Khmer Krom. It's said to be the site of a race between a man and a woman to see who could dig the pond the fastest. The woman won, and the pond remained as it was.
Nearby, there's a Khmer temple with a museum showcasing Khmer culture.
I'll include more information next time.
