Beting Aceh Island represents a distinctive marine tourism destination located in Rupat Utara District, Bengkalis Regency, Riau Province, Indonesia. This uninhabited island, covering approximately 2-4 hectares in the Malacca Strait, is renowned for its unique geological phenomenon known as "singing sand" or "whispering sand," which produces audible sounds when disturbed by human contact. The island's formation is attributed to natural sedimentation processes, where oceanic currents have deposited sand particles over extended periods, eventually creating this distinctive landmass. The island's primary attraction manifests during low tide conditions, when extensive white sand formations emerge, creating temporary land bridges connecting Pulau Beting Aceh to the adjacent Pulau Babi. This tidal phenomenon transforms the seascape into expansive sandy terrain comparable to the size of a football field, surrounded by pristine blue waters and complemented by coastal casuarina vegetation. Access to the destination requires a 30-45 minute speedboat journey from Tanjung Medang Village. As one of Indonesia's outermost islands in the Malacca Strait, Pulau Beting Aceh serves as a significant ecotourism destination that offers visitors opportunities for nature observation, photography, and marine recreation activities. The destination's unique combination of acoustic sand phenomena, tidal geography, and pristine marine environment positions it as a noteworthy addition to Riau Province's tourism portfolio.
