History

Map of Southern Vietnam in 1838, taken from An Nam Đại Quốc Họa Đồ (Map of the Great Kingdom of An Nam) by French missionary Jean-Louis Taberd.

According to Đại Nam nhất thống chí by Trịnh Hoài Đức, the two mountains, Big Mountain and Small Mountain (Núi Lớn và Núi Nhỏ in Vietnamese) in Vũng Tàu, were also called Gành Rái Mountain as the otters (Rái here means the otters) often gathered there, means the Bay of Otters. Gành Rái Bay probably also took its name from there because it was located further inward from the sea entrance after passing those two mountains from offshore upstream towards Gia Định.

The bay's bottom is relatively shallow, so large ships cannot easily enter or exit. To allow large merchant ships to reach Saigon on the Saigon - Vũng Tàu shipping channel, the bay's bottom was dredged to maintain a depth of 8.5 meters or more. The shipping channel through Gành Rái Bay is 400 meters wide and has buoys for ships to identify when navigating.

Besides its important role in waterway transportation, Gành Rái Bay is also a large fishing ground with many aquaculture farms raising shrimp, fishes, and bivalves such as clams and oysters. The Cần Giờ mangrove forest is a biosphere reserve recognized by UNESCO that nurtures young shrimp and fish. People living along the bay also use the bay's natural terrain to make salt fields. Fishermen often use basket boats when they off shore.
