The name means "ghost" in Malay, but there is nothing eerie about what draws people to Pulau Hantu. What you find here, just a short sail from the southern coast of Singapore, are some of the well-maintained coral reefs in the country, waters that shift from deep blue to startling clarity as you approach the shallows, and an atmosphere that feels entirely removed from the city humming away in the distance. The Hantu Glow is a single-day sightseeing cruise that takes you into this underwater world and the scenic waters surrounding it, offering a side of Singapore that sits just below the surface, quite literally, waiting to be discovered.
