As the summer continues to dwindle away into fall, the North Shore remains one of the best places to get in the water. Last month we explored Waimea Bay, but there are plenty of other options on the North Shore when it comes to diving and exploring. One of my favorites is the Haleiwa Trench. Whether you want to shoot big or shoot small, this is a good place to explore.

The Trench is relatively easy to find. First navigate to Haleiwa’s Ali’i Beach Park. I usually park near the Baywatch building and walk out on the beach to the right side of the point. There is a shower

here for when you return and need to wash your gear and self down. The entry is a bit shallow and you will find yourself skimming along a seemingly endless shallow plateau before it gradually gets deeper. Be on the lookout. There is a lot of algal growth in the shallow areas, sometimes blocking out the nooks and crannies where juvenile critters tend to hide. Have a look around in these areas—you can often find

some interesting critters hiding behind the vegetation. After a bit of swimming, the water gets a bit deeper before you literally go over a cliff. This is where the place gets its name.


Interesting critters


The cliff drops down 70-80 feet into what is known as the Haleiwa Trench. The area around the drop is one of my favorite places. Honu abound around this margin—some on the precipice of the

range is beyond me. But the monk seal rose ten feet to the surface to get air before going on its way to the bottom of the trench to visit our other friends. I guess everyone has a schedule to keep…


Crescent octopus
What I believe to be a crescent octopus, Octopus hawaiiensis, lurking in the reef.


Although you can see some large animals in this area, it’s also fun to play around at the small end of things and shoot macro. There are plenty of small ambush predators like the arc-eye hawkfish

In addition to the regular daytime diving, the nighttime diving at the trench can be exceptional as well. Go at night with friends and bring a light. Be ready to see a lot of the nighttime critters—


Imperial nudibranches

nudibranches, mollusks, eels, tako, crabs, etc. Either way you go, day or night, wide angle or macro, Haleiwa Trench has a lot of interesting critters to see and lots of area to explore.
