Why dive here
With 238+ marine species recorded in the area - including blacktip reef sharks, giant moray eels, pygmy seahorses, seahorses and sperm whales - Sentinels offers some of Sulawesi's richest diving. Water ranges 29-31°C, warmest June, October, November.
Sentinels, off Sulawesi, really stands out. It's not your typical wall or bommie site; instead, you get this unusual collection of 26 pinnacles, scattered along a sloping reef. Some shoot up like slender fingers, others are more like stocky buttresses, often tiered with those big acropora table corals. You’ll spend most of your time between 5 and 12 meters, poking around the overhangs where we’ve seen white fox-tail tunicates clinging on. It’s a great spot for macro life and just enjoying a relaxed, shallow dive, particularly if you're keen on exploring an uncommon reef structure.
