Article, Photos and Video by William Drumm

Imagine swimming through a blue-green sea teeming with life. Sunbeams cascade through kelp fronds as harbor seals curiously approach and sea lions dart past. Schools of rockfish swirl around the towering kelp, and on the seafloor, are giant sea slugs, octopuses, brittle stars, and something unexpected at every turn. Monterey Bay, California, offers an unparalleled cold-water diving experience, and is home to some of the most diverse marine ecosystems on the planet.

Why Dive in Monterey Bay?

Monterey Bay is a destination that appeals to all kinds of divers. Whether you’re just starting your scuba journey or have many years of experience, this place has something for everyone. Freedivers, macro enthusiasts, tech divers, and those drawn to large marine animals will find plenty to explore. The bay’s nutrient-rich waters support thriving ecosystems, making it one of the best locations for observing marine life in its natural habitat.

The kelp forests are the centerpiece of diving here, creating a unique underwater landscape. The accessibility of dive sites and the lively local dive community further enhance the experience. I spent several years in Monterey and enjoyed countless hours diving, filming, and photographing the underwater highlights. Some unforgettable moments include witnessing humpback whales lunge feeding in the middle of our dive site, and playful sea lions swirling through schools of fish. Monterey Bay’s unpredictability ensures no two dives are ever the same.

Nudibranchs and Side Gill Slugs: Vibrant and colorful, these sea slugs are abundant in the area and make for stunning macro photography subjects.

Top Monterey Bay Dive Sites

Breakwater Cove

Breakwater Cove is one of the most popular shore dives on the West Coast of the USA. It’s ideal for beginners and photographers due to its easy entry and abundant marine life. Explore rocky bottoms teeming with sea lions, sandy flats, and lush kelp forests. Harbor seals and sea otters are frequent visitors, and you may even spot octopuses and colorful nudibranchs. This site is perfect for a relaxed dive while still offering plenty to discover.

McAbee Beach

McAbee Beach is a shallow and accessible site, great for observing playful harbor seals and larger fish, like lingcod and cabazon. It’s also a fantastic location for freedivers and macro photographers. The varied terrain offers opportunities for exploration and observation of marine life in close quarters.

Monastery Beach

Monastery Beach, located in Carmel, is a favorite for advanced divers. Known for its steep beach and challenging entries, it’s not for the faint of heart. However, the rewards are incredible: kelp forests with visibility up to 80 feet on a good day, and the chance to encounter large animals like gray whales. This site is ideal for those seeking both beauty and a sense of adventure.

Point Lobos State Natural Reserve

Point Lobos offers easier access than Monastery Beach and is one of California’s most protected marine environments. Reservations are required, but the effort is worth it. From thriving kelp forests to playful seals, this site offers some of the most pristine underwater experiences in the region. It’s also an excellent location for boat dives, with the potential for encounters with larger pelagic species.
