About this site
Sumpat Reef lies in Indonesian waters near the Riau Islands, in the area between the Malay Peninsula and Sumatra along the busy Singapore Strait shipping lanes. It has a maximum depth of around 10 metres and is considered suitable for beginners, making it a shallow reef dive rather than a deep or technical one.
