I’ll wager most Central California divers did at least two of their certification dives at the
Breakwater. This dive site is the most protected in the Monterey Bay Area and is an ideal spot
for open-water certification dives. As diver’s skills improve, most divers migrate away from the
Breakwater to find more challenging sites and to avoid the crowds. However, as more and
more divers take up underwater photography, the Breakwater is now known for its incredible
collection of photogenic marine life. Even within an area that is well known for its excellent
macro photography, the Breakwater stands out as one of the best. I recently dived the site
after a long hiatus and was happy to find that all of my favorite critters were there in

The Breakwater sits at the southern end of Cannery Row, an area rich with history. The Coast
Guard built the jetty in 1934 at the site of the old Coalinga Oil & Transportation pier, and the
jetty extends 200 yards from the end of the pier. San Carlos Beach and Park is to the north of
the pier and was formerly the site of the San Carlos Canning Company, which burnt in 1956.
The E. B. Gross Canning Company was located just to the north of the San Carlos facility,
and the Monterey Bay Inn sits on the north side of San Carlos Beach on the site of the former
Enterprise Packing Company.

Divers enter the water from San Carlos Beach on the north (ocean side) of the breakwater.
Extending from the beach is a sand bottom that gradually slopes down to a maximum depth
of 60 feet along the breakwater. To the left of the Breakwater stretches a rocky patch reef that
extends all the way to McAbee Beach. Scuba classes are normally conducted here. Divers
will find kelp-covered rocks with an interesting assortment of hermit crabs, small fish, and
The Breakwater itself was fabricated from large granite blocks that create a labyrinth of small
crevices and passageways in which a virtual army of sea creatures can find shelter. Striped
shrimp hang on the undersides of rocky ledges and monkeyface pricklebacks peer out of
holes. On this recent dive there were a few 9-inch abalones back in cracks that were too
small for a sea otter to fit into.
Small shrimp, juvenile abalone, flatworms, a huge variety of nudibranchs, and an assortment
of small crabs will make macro photographers think that they are in heaven. Orange cup
corals dot many of the rocks and make great photographic subjects. These little corals
possess fluorescent pigments in their tissues and cause the rocks to glow orange.
Rockfish and surfperch hang out in the kelp. Living on, and feeding on the kelp itself is an
assortment of photogenic subjects, including brilliantly colored blue-ring top snails and bright
red kelp crabs.
One of the biggest attractions that the Breakwater has to offer is its large colony of California
sea lions. The last half of the breakwater itself is not accessible to people from the wharf and
is a favorite hauling-out location of these large and noisy mammals. Sometimes they will stay
on the jetty and avoid divers, and at other times they will dive down and check us out. Diving
with marine mammals is a delightful experience.
While most sand bottoms are generally uninteresting, this one is dotted with sand dollars, sea
pens, and aggregating anemones, many of which have intricately colored radial disks.
Translucent tentacles of white, orange, and purple tube-dwelling anemones wave to-and-fro in
the surge. Sand-rose anemones are found in deep water near the end of the breakwater.
Look for a large anchor in shallow water near the entry as you swim along the breakwater.

There are quite a few rainbow nudibranchs here and they are a real treat to discover. These
deep red mollusks are the largest
nudibranch found in California waters.
They owe their existence to the tube
anemones, on which they feed, mate,
and lay their eggs. When disturbed, they
fly through the water with an undulating
motion California Spanish dancer.
So if you have not dived the Breakwater
since you were certified, I encourage
you to check it out. All of the diver
support services you could ever ask for
are within an easy walk, and the sea
lions and little critters make for a very
enjoyable dive.

General Guidelines for After Work & Night Dives: To participate in after work dives or night
must carry a minimum of two lights, one main light and one marker light (usually attached to
valve). The dive must be terminated if a person experiences a malfunction of his/her light(s).
Carrying three lights is strongly recommended so that dive team can continue the dive if one
