Very easy shore dive, local PADI instructors take students here for their open water cert dives. Lots of turtles, fishes... also neat swim-throughs in the reef. Nothing too nasty, maybe the occasional reef shark, though I've never seen one here. A great O'ahu dive. But it's crowded on the summer weekends... though Three Tables (another dive site) is right next door, so there's plenty of space in the water, even if parking is bad.

Shark's Cove at Kalalua Point is another must-dive site for Oahu. The entry is easy, and it's just a short kick to get outside the reef.  Kids and snorkelers will find the cove perfect for their activities. Rocky coastal area & tidal pools teeming with small fish for snorkeling, plus showers & restrooms. Off Kamehameha Highway on the North Shore in the Waimea area.

Why is it called Shark's Cove? Because the outline of the reef from above looks like a shark.

Shark's Cove is also known as Pupukea

Shark's Cove

I've dived sharks cove at least 6 times.  Unless the conditions are exactly right the experience is horrible.  When visibility is good and there isn't a current, I'd have to say it's one of my favorite spots.  Unfortunately it's hard to get those conditions.  I saw a lot more fish snorkeling there than I did while diving.

#2 - Shark's Cove

This is the beach where Burt Lancaster and Deborah Kerr got hot and heavy, making out in a wicked beach break in the movie "From Here to Eternity". (I think I would've found the waves a little distracting. Seriously, they're getting their backsides handed to them big time and I doubt they enjoyed filming that scene at all.) It's also called Cockroach Cove by more recent generations, not sure why.
It's a very nice dive site. Use caution for the current and waves which can be treacherous. Only go when it's very docile. Rocks may be slippery as well.
After swimming out shallow cove, turn a little north and find the big crack that leads into the actual blow hole. If there's any waves at all, stay away from blow hole. Seriously, people have died in there (usually by getting sucked in from above, though) and you don't want to get stuck inside. Just use your head. If wave action is okay, it's pretty cool dropping down into this itty-bitty canyon.
Pretty good chance to see green sea turtles, spotted eagle rays, octopus and maybe a white-tip shark.

At first glance, Halona Blow Hole appears to be an easy, protected site for both snorkelers and divers.  However, a list of SCUBA fatalities since 1971 shows that more fatalities by far occur at Halona Blow Hole than any other dive site in the state.   First off, the sea cliffs that make this stretch of shoreline so great for diving also precludes any easy exit sites.  This, coupled with the strong current, slippery rocks, waves on the ledges, and lack of lifeguards makes this coast one of the most hazardous on the island.  Be especially careful on this stretch of coast!  The nearest facilities are at Sandy Beach to the North, so take plenty of water.

Halona Blow Hole, on the South Eastern shore,  can be found at a large touristy turn out between Hanauma  Bay and Sandy Beach Park.

Halona Blow Hole

The hike down and swim out past the current can be exhausting but it is well worth it.  This is one of my favorite spots; it's very secluded with lots to see.  However, make sure there isn't any surf or it could get VERY Dangerous.  Also watch your vehicles in the parking lot because they do tend to get broken into.
