Island escapes easily reached from Singapore - SilverKris

"A quiet southern-island beach escape known for its powdery white sand, calm blue waters and minimal crowds, ideal for picnics, swimming and family-friendly water sports such as kite-flying, beach volleyball and snorkeling. The island is also home to many friendly stray cats. Access is straightforward by ferry from nearby piers or via the walking causeway from a neighbouring isle, and while the islet itself is uninhabited there are now tiny rental units available for overnight off-grid stays. There are no food stalls on site, so visitors should bring their own provisions." - Claire Knox and Levin Tan
