Alternative Reef
Why dive here
With 142+ marine species recorded in the area - including barracuda, blue-spotted stingrays, eagle rays, sea turtles and sperm whales - Alternative Reef offers some of Sipadan's richest reef diving. Water ranges 28-31°C, warmest August, September, October.
Alternative Reef is a good alternative to some of Sipadan's busier spots. It's a slope, mostly soft coral, with lots of smaller reef fish darting around. We usually see green turtles here, sometimes resting, sometimes just cruising past. If you’re looking for a slightly quieter dive in Sipadan, this is a solid choice.
