Back Beach (Bãi Sau, formally Bãi Thùy Vân) is the main beach of Vũng Tàu city and the primary weekend coastal destination for Ho Chi Minh City's population of around 10 million people.
Origin of the Names
It gets its common name from its position on the 'back' side of the city, facing away from the main downtown frontage, in contrast to Bãi Trước (Front Beach) on the western side. The more poetic name Thùy Vân has a couple of competing folk explanations involving clouds - one likens them to a soft silk ribbon drooping toward nearby Nghinh Phong Cape, another describes them at dawn stretching level with the horizon.
The Beach and Thùy Vân Street
The beach stretches a little over 8km along the eastern face of the Vũng Tàu peninsula, facing the open East Sea, and is backed by a dense strip of hotels, restaurants, and beach services that has developed over decades into a concentrated resort district. A major urban redevelopment project along Thùy Vân street, begun in late October 2024, has since added flower gardens, tall coconut palms, a completed beachfront walking path, and decorative arches, shifting some of the space from purely fee-based services toward a more open public gathering area - part of why the beachfront feels noticeably more polished than it did a few years ago.
Vũng Tàu is approximately 120km from HCMC and accessible by highway in 2 hours or by high-speed ferry in around 90 minutes - close enough for a Saturday-Sunday trip without an overnight, which is how most visitors use it.
Beach Conditions Through the Year
The beach itself is wide and sandy, lined with umbrellas and sunbeds on weekends, and the water is generally swimmable in the dry season. It's worth being upfront, though, that this isn't a pristine beach: roughly August to November, Vũng Tàu's coastline faces a real, well-documented seasonal problem with water hyacinth and floating debris washing in from the Mekong river system, sometimes in large enough quantities to cover multiple kilometres of shoreline before cleanup crews can clear it - over 5,000 tonnes were removed from local beaches in 2025 alone.
Outside that window, and especially in the dry season, the beach is in much better shape, and the seafood restaurants along Thùy Vân street remain a genuine draw in their own right regardless of season.
