Introducing Lang Co Beach
Lang Co is an attractive island-like stretch of palm-shaded white sand, with a crystal-clear, turquoise lagoon on one side and 10km of beachfront on the other. As a beach resort it's more geared to Vietnamese day trippers than Western travellers, but if the weather's nice the ocean is certainly inviting (if you stay away from the central section, which could be cleaner).
High season is April to July. From late August till November rains are frequent, and from December to March it can get chilly.
