Cần Giờ is Ho Chi Minh City's southernmost district - a peninsula of mangrove forest, fishing communities, and open coast that sits within city administrative limits but feels completely removed from the urban density of Districts 1 through 12. The traditional focal point for weekend visitors from Saigon has been the beach at Cần Thạnh town, often called Bãi biển 30/4 - a stretch of dark-sand coastline on the East Sea, backed by casuarina trees and a strip of seafood restaurants, with the Cần Giờ Mangrove Biosphere Reserve behind it.
As of the mid-2020s, though, that beach has been fenced off as part of an active land reclamation and resort construction project (Vinhomes Green Paradise Cần Giờ, reportedly around 2,870 hectares), underway since 2025 in phases, with some infrastructure reportedly expected around 2029 and the wider development targeted for completion around 2030 - so the open, walkable beach described in older write-ups isn't currently accessible in its traditional form, and visitors are pointed instead to a handful of nearby alternative spots, most commonly the old ferry pier area (Bến Đò Cũ) in Cần Thạnh.
Even before construction, this was never a pristine, white-sand destination - the water and sand are naturally dark from silt carried by the Đồng Nai and Sài Gòn river estuaries - but it has long served a specific function as the closest swimmable coastline to one of Southeast Asia's largest cities, valued more for the seafood, the mangrove landscape, and the change of pace than for classic beach scenery.
