Hòn Khô - literally 'Dry Island' - is a small uninhabited island approximately 4km off the coast of Nhơn Hải commune, northeast of Quy Nhơn city in Bình Định province. The island is characterised by dramatic granite boulder formations, clear turquoise water, and coral reefs accessible by snorkeling and SUP. At low tide, a tidal path emerges between the island's two sections - one of the most photographed features of Hòn Khô.
From May to July, the surrounding sea floor transforms with rong mơ (golden seaweed) that carpets the shallows in vivid yellow and amber, creating what visitors describe as a 'golden ocean field' - a seasonal spectacle unique to this stretch of Bình Định coast. The island is the most popular day trip from Quy Nhơn and pairs naturally with Kỳ Co and Eo Gió on a northeast coastal loop.
