You can keep your scents of newly-cut grass, baking bread, or a steaming cuppa. The greatest smell in the world is, without question, the fresh caress of salty sea air. How lucky, then, that the best sensation is the tickle of warm sand between your toes. And the best sound? The soothing hiss of waves breaking on a beach. We tend to forget these sensations in Singapore – despite the fact that we live on an island. Luckily, there are three reminders just a short ferry-ride away: St John’s Island, Lazarus Island and Pulau Seringat.
