Cần Giờ is a coastal district of Ho Chi Minh city, 50 km (32 miles) form the city center. Can Gio tourism is famous for its intact mangroves and pristine beaches without many rather-touristy services. Also, the seafood here is cheaper than in Vung Tau (a more popular beach near Ho Chi Minh city). Though the sea is not crystal blue due to the water outflux from mangrove but not too bad to jump in. Ideal for a one-day getaway weekend!
