Blue Corner in Palau is one of the most thrilling reef dives anywhere, a plateau and wall where powerful currents draw in a stunning concentration of marine life. Divers hook onto the reef with a reef hook and hang in the flow while sharks, jacks and barracuda stream past in the blue. Palau, a remote archipelago in the western Pacific, is a pioneer of shark conservation, and it shows in the sheer number of predators here. When the current runs, Blue Corner delivers action that few sites on Earth can match.
What makes it special
Blue Corner is a reef point that juts into open ocean, so incoming currents hit it head-on and rise up the wall. That upwelling brings nutrients and concentrates baitfish, which in turn pulls in the predators.
The reef hook technique lets you stay put and simply watch the show without finning against the flow. It is one of the definitive drift and big-animal dives.

Marine life you may see
Grey reef and whitetip sharks are the stars, often seen in numbers, along with huge schools of jacks, barracuda and snapper. Napoleon wrasse frequently approach divers, and turtles and eagle rays are common.
On the reef top you find healthy coral, anthias clouds and the occasional passing pelagic. The density of life here is what keeps divers coming back.
Level and conditions
Because currents are strong and variable, Blue Corner is best for experienced divers comfortable with drift diving and reef hooks. An Advanced certification and solid buoyancy are strongly recommended.
Depths run from around 8 meters on the reef top to 30 and beyond on the wall. Water is warm and visibility is generally excellent, though conditions change quickly with the tide.

Best time and how to reach it
Palau can be dived all year, with the drier months from November to April often offering the best visibility. You reach it by flying into Koror, usually via hubs in Asia or Guam, then diving with local operators or a liveaboard.
It is a genuinely remote destination, so most visitors dedicate a full trip to Palau and its nearby sites like German Channel and the Rock Islands.
Shark encounters near home
You do not have to cross the Pacific to hang in the blue with sharks. On the walls of Isla Fuerte, hammerheads and whitetip sharks pass along the deep site of Bushnell, in the warm continental Caribbean of Colombia.
Nautilus is a PADI AWARE conservation center, running Reef Check monitoring and lionfish control, so your dives support the reef you enjoy. Discover our sites on the interactive dive map.
