This area is nicknamed by many local divers as the "Pinball Machine", due to the turbulent surge near the rocks. Diving at Blowhole requires almost perfect conditions and surf above 1-2(3) feet makes this location very hazardous for even the more advanced divers. The Molokai Express runs offshore and can be a treacherous and swift current. It is best to stay within 100 feet of shore and to try to dive Blowhole at slack or incoming tide. Visibility at this site is generally very good when the surf is small and the best diving is found around the point to the right. To the right you will find some interesting ledges and cliffs that seem to drop from 20 to 60 feet. Sea life in this area ranges from large green sea turtles, goatfish, Spanish dancers, and a large assortment of Butterflyfish. During certain times of the year you can hear the sounds of whales and dolphins offshore. Be cautious to stay away from the edge of the cliffs and rocks during entry and exit, especially to the right of the cove near the point.

This is one of my favorite shore dives on Oahu. You'll likely see honu (turtles), eels, frog fish (if you look very closely), and a variety of reef fish. However, you need to know what you're getting in to--accessing the shore from the parking lot requires a short but steep walk that's pretty slippery when it's wet. The entrance/exit point is rather narrow with rock ledges on either side (the drop point is just after you pass the rocks-- don't even try it if the surf is higher than 2-3 feet, as the surge can be wicked (and slam you into the rocks), and visibility won't be as good. Nonetheless, it's a fantastic dive if the conditions are right. Have fun!!
