What is Point Loma diving like?

Point Loma, often overshadowed by La Jolla's popularity and Wreck Alley's hype, is San Diego kelp forest paradise.

A prized San Diego scuba diving gem, this area teems with sea life and kelp forests. Here's what you'll find while diving in Point Loma, in a nutshell:

  • Kelp Forests - a healthier stretch when compared to La Jolla kelp forest
  • Canyon/Walls - sometimes a short swim from nearby kelp lines
  • Wreck-ish - a random set of wrecked train wheels lying on a canyon

Where can you dive in Point Loma?

Point Loma dive sites are generally separated into two main areas, with some overlap between them: Kelp Beds and Sea Cliffs.

At the northern end of Point Loma lies the main area of the San Diego kelp forest (locally referred to as 'Kelp Beds'), a combination of shallow sandy bottoms, rocky ledges, and giant kelp and sea palm clusters.

This gradually slopping 6-mile stretch of San Diego kelp forest has so many unique dive sites, one could dive here their entire life and not get bored.

The Sea Cliffs, at the southern end of Point Loma, tend to be deeper dive sites along underwater walls.

These cliffs, formed during the last ice age, were dug out by thousands of years of wave action and used to be out of the water.

Now a diver's paradise, slot canyons, large overhangs, and other dramatic features awe even the most seasoned divers.

āœØ KELP DIVING SAFETY TIP: If you feel like you got stuck on kelp, try not to spin around to untangle yourself. Instead, signal to your buddy to assist you while remaining still. It will be much easier for them to set you free.

What marine life calls Point Loma home?

The combination of rocky bottoms, ocean currents, and the protection of kelp forests has formed the ideal environment for life to flourish in Point Loma.

Divers often encounter horn sharks, moray eels, bat rays, sea stars, octopus, and spiny lobster hiding amongst the rocky structure.

Macro photographers will have their hands full, with over 20 species of nudibranchs in the area and loads of other small creatures to find and photograph.

Up above in the kelp canopy, larger creatures such as sevengill sharks, giant sea bass, schooling blacksmiths, and even yellowtail can all be found in Point Loma.

āœØLOCAL TIP: Be ready to get in the water after your crew dive brief. This will give you the best chance of seeing larger creatures that may get spooked by big groups of divers.Ā

Point Loma Dive Sites

Point Lomaā€™s 6-mile coast offers over 20 dive sites, which we divide into two main zones: the Point Loma Kelp Beds, featuring giant kelp forest and reef life, and the Point Loma Ancient Cliffs, where kelp gives way to steep cliffs descending into about 100 feet of water. Below, we highlight the key differences between these areas and share some of our favorite dive spots in each.

Point Loma Kelp Beds

Depth: 60 ft (18 m)
Level: Open Water

Point Loma is known for having one of the largest and healthiest kelp forest extensions of the whole Southern California coastline.

The luscious local kelp canopies tower over big boulders, overhangs, ledges, and cracks, creating the perfect environment for a diversity of marine life to call home.

For dive boats, spot specific trips are hard to pin down due to dive conditions and boat traffic. Notable spots include 6 Fathoms, New Hope Rock, Horsehead Reef, Goal Posts, Broomtail Reef, NRAD, and North/South Pipe.

Point Loma Ancient Cliffs

Max. Depth: 100 ft (30 m)
Level: Advanced

During the last ice age, when the sea level was 100 ft lower, the Sea Cliffs were battered and carved by relentless waves and tides. Nowadays, these cliffs lie between 65 ft and 110 ft underwater.

As with Point Loma Kelp Beds, boat trips are kept to a general area. Some of the notable spots within the area include Dino Head, Train Wheels, Three Fingers, and Main Wall.

Most of the sea life will be congregated within 10 ft (3 m) inside or outside of the kelp line. As you venture deeper into the kelp forest, activity slows and fish can be sparse.

6 Fathoms

Depth: 40 - 60 ft (12 - 18 m)
Level: Open Water

At the north end of Point Loma Kelp Beds, this area has some of the densest sections of San Diego kelp forest.

Underwater, about 0.5 mile from shore, a large flat portion of the rocky bottom abruptly ends in a 5 ft (1.5 m) tall ledge running north to south. All along this ledge, ocean life thrives.

Divers can encounter lobsters, horn sharks and other bottom-dwelling creatures hiding amongst the rocks. If you venture East underneath the kelp forest canopy, you may even encounter a giant sea bass or sevengill shark cruising around.

We consider this our ā€œhouse reefā€ as this is a relatively easy dive, with the chance of seeing most of the creatures found on the San Diego coast. Itā€™s a local favorite!

Dino Head

Max. Depth: 65 - 100 ft (19 - 30 m)
Level: Advanced

What makes Dino Head one of San Diego's most iconic dive sites is a large pinnacle rising of the sea cliff in the shape of a T-Rex head, looking out over the dive site.

Similar to other sites along the sea cliffs, the top of the wall sits at 65 ft and descends to the sandy sea floor at 100 ft. This dinosaur head sits to the East, up a wide sand channel running toward shore.

But donā€™t forget to check out the holes and ledges on your way there! These ridges are home to more nudibranchs than we care to count.

Divers have a wide range of structures to explore at different depths of this dive site, so dive planning is key.

New Hope Rock

Depth: 20 - 35 ft (6 - 11 m)
Level: Open Water

Possibly the shallowest dive site in Point Loma Kelp Beds, this rock is home to a large density of fish and other sea life.

Excellent for those new to California diving, New Hope Rock rises up from the seabed, in 35 ft (11 m) of water, putting the top of the structure only 10 ft (3 m) from the surface.

The main rock is surrounded by sea palms on all sides, except for a few cracks and crevices. If you still have plenty of air, there is a second rock pinnacle near the main structure to explore.

Several holes and an overhang were carved out by ocean currents, now lined by anemones and other invertebrates. Make your way along the bottom and you may find lobsters, octopus, and even scorpionfish.

Train Wheels

Max. Depth: 65 - 100 ft (19 - 30 m)
Level: Advanced

Very close to the southern tip of Point Loma, the shelf quickly ends and a wall drops from 65 ft down to 100 ft.

Lying in one of these slot canyons, around 100 ft down, are two full-sized sets of train wheels, now confined to this canyon by prevailing currents. This canyon, known as ā€œthe crackā€ is wide enough for several divers at its base, but slowly narrows near the top of the canyon wall.

Now you may be asking yourself, ā€œHow did train wheels end up in a canyon almost a mile offshore?ā€

Although no one knows exactly how these train wheels got here, there is some speculation they were used as part of a NAVY exercise, or possibly for ballast on a smaller cargo ship.Ā Either way, this site is one of the most unique dives in the Sea Cliffs area.

Horsehead Reef

Depth : 45 - 60 ft (13 - 18 m)
Level: Open Water

This shallow underwater ecosystem is a favorite for macro photographers, teeming with nudibranchs and other small critters that thrive in the rocky terrain.

A prominent rock here protrudes from the bottom, resembling a horseā€™s headā€”giving the site its name.

The main rock is surrounded by smaller rocky outcrops, with ledges and holes providing shelter for lobster, octopus, moray eels, and other reef creatures.

Moving slowly is recommended; paying close attention to the boulders can reveal camouflaged inhabitants, like scorpionfish or kelpfish, blending into the background and waiting to be spotted by careful divers.

This site is a must for nudibranch fans!

7 Fathoms

Max. Depth: 65 - 100 ft (19 - 30 m)
Level: Advanced

7 Fathoms, or Three-Fingers Reef, is a bustling underwater habitat with rocky fingers that extend into deeper waters, creating a vibrant space teeming with marine life.

The strong currents are a food source to filter feeders, which in turn attract diverse fish, including calico bass, sheepshead, and barred sand bass.

In the deeper crevices, divers may find guitarfish nestled away, while smaller fish, like black perch and opaleye, inhabit the shallower crevices.

Nudibranchs and other macro critters are plentiful, making it a popular spot for photographers. Lobsters and rock scallops hide among the rocks, though many lobsters are undersized.

Strong currents and surge create both challenges and a lively environment.

Other Point Loma dive sites

Other notable dive sites south of Point Loma and towards the Mexican border include USS Hogan shipwreck (not part of Wreck Alley), Missile Tower wreck (not part of Wreck Alley), and S-37 submarine wreck (not part of Wreck Alley).

We don't usually venture out to these sites as they're all past recreational diving limits.

Hands down the best scuba charter I've ever experienced (and have dove in Florida, Panama, Brazil, Hawaii, Cozumel). Zach and the crew are incredibly skilled, safe, and kind. The captain even made homemade bluefin ceviche in addition to ensuring hot soup and hot shower water between cold November dives. I can't recommend their dive charter to Coronado Mexico enough, and can't wait to dive with Waterhorse again already!

Took a dive trip out to Coronado Islands. Impressive dive company with a phenomenal team. They have top tier service getting into your gear and into the water. They try to get you as much time with the sea lions as possible! By popular demand, we got to do the sea lion dive twice!! Even got to do some whale watching on the way back. 1000% recommend!!

Two good dives yesterday on Orion. First was in the kelp off of PT Loma. Vis was 20-25 ft. Second was on the Rube-E. Had to work through a green layer, but vis opened to 15 ft at the hull. The crew was great as usual. This dive was to test a new backplate and bladder + wt check.

Iā€™ve booked three boat dives with Waterhorse and my California dive experience has been excellent . I did chose the option to hire a dive guide. The guides were very helpful assisting with weight checks. A big thanks to Ben and Hunter for guiding me through kelp forest and wrecks. I still have another dive left with this company as im writing this review. Iā€™m usually a warm water diver with a 3 mm suit on. I would hope that all cold water dive operators operate like Waterhorse. If diving in San Diego do chose this company. Oh they actually have warm soup and snacks after the first dive. So far all the heads (toilets) are functional. Warm water showers as well. šŸ‘Œ

Waterhorse Charters truly exceeded my expectations and provided the best dive charter experience Iā€™ve ever had. From the owners to the crew, everyone is top-tier. I had the pleasure of meeting Zach, one of the owners, at the Scuba Show, and I corresponded with his wife Karina over email to make changes. The entire booking process was seamless and professional. My girlfriend, who often accompanies me on dive trips, mentioned that Captain Charles was the nicest captain sheā€™s ever met. The divemasters I had, Brandon and Jon, are probably the best dive guides Iā€™ve ever had. I can confidently say they gave me my favorite dives of all time so far. I initially heard about Waterhorse Charters from an instructor in Hawaii and the Azul Unlimited YouTube channel, so my expectations were highā€”and they met or exceeded every one of them. If youā€™re looking to dive cold water in the San Diego area, Waterhorse Charters is the way to go.

I recently had an incredible experience with Waterhorse Charters on a trip to the Coronado Islands! The crew made the entire day exceptional from start to finish. Gaby was attentive and ensured that everyone felt welcome and prepared, offering all the support we needed throughout the trip. Ben was incredibly knowledgeable about the islands and their marine life, making every stop interesting and educational. Brandonā€™s professionalism and friendly attitude added to the overall comfort and enjoyment of the journey. And a big shout out to Charles, who kept everything running smoothly and made sure we had a safe and memorable adventure. Thank you, Waterhorse Charters, for a wonderful day on the water. I highly recommend this experience to anyone looking to explore the beauty of the Coronado Islands with a top-notch crew!

Why go somewhere else? The location of the boat means you get in and out of the harbor quickly. Thorough safety and dive briefing. The hot shower ensures you're warm and comfortable for second and third dive. Don't underestimate the wonder of the hot soups. They convert surface intervals from a mere necessity to something to look forward to and warm you up for the next dive

Zach and the Waterhorse crew are outstanding and safety conscious dive professionals! When I want to go boat diving I go to Waterhorse first. They take us to the best sites and offer in depth dive site briefings and always have the best interest of the divers! If you only have one day to dive go to Waterhorse!

This is the best dive company in San Diego hands down. I have been diving with Waterhorse charters for almost three years now and every trip it never ceases to amaze me how helpful, kind, and attentive the crew is. Zack helped out last week to get lobster season rolling and I came home with four of them! Donā€™t look anywhere else if you are wanting to dive in San Diego.
