Best Aquarium in Northern California

1. Ocean World

South Crescent City, California

Located at the very top of California, right under Oregon, Ocean World was once a floating barge with sea life displayed inside and is now a sprawling ocean facility on dry land with a variety of sea life, including sharks, seals, sea lions, and stingrays. Forty-five-minute tours embark every fifteen minutes through this beautiful, natural-light aquarium experience.

The Touch and Feel Tide Pool contain many creatures native to the rocky shorelines of the pacific northwest. Find out what a sea urchin feels like, and touch a live clam and a sea cucumber. Kids and adults enjoy this unique experience of getting closer to local nature, making this a top-best aquarium in California.

Upon entering the aquarium, you’ll see the sharks, sea lions, stingrays, and more who make this place their home. Many of them are native to the area, and your tour guide will share interesting facts about each of them as you go. And if you’re feeling brave, you can actually pet a real shark!

Wrap up your incredible experience with a special seal or sea lion performance where you can watch the animals have fun with all sorts of antics and shenanigans. You can also learn about the fantastic training process that enabled these animals to remember how to do each of these tricks, which is a top reason why this aquarium is a candidate for the best aquarium in California.

Keep in mind that you can only visit this aquarium if you go through the guided tour. Ocean World takes pride in its guided tour experience, which sets them apart from other aquariums, so individual perusing is not allowed.

2. SeaQuest Folsom

Folsom, California

If interacting with the animals is the main attraction of aquariums, you need to experience the SeaQuest Folsom. Truly a land and sea adventure, there are about as many land animals as ocean animals here. A remarkable aspect of SeaQuest is they let you touch and feed just about every animal there!

Visit their Amazon Rainforest, Pirate Island, Egyptian Desert, Mayan Jungle, and Caribbean Cove to feed sharks, birds, stingrays, crocodiles, and tropical animals. You’ll get to learn all about each of the animals and the ecosystems they inhabit in different parts of the world. And for the most epic exploration, rent some snorkeling gear and hop into the 36,000-gallon exhibit filled with reef sharks, stingrays, and hundreds of tropical fish.

Some of their animal interactions are just part of regular admission, but others, like the snorkeling with stingrays adventure, cost extra. Additional activities include handling snakes, holding a giant blue-and-gold macaw, playing with a sloth, meeting porcupines, feeding otters, and more. There’s a good chance this is the best aquarium in California.

SeaQuest is perfect for individuals, friend groups, families, and field trips. They offer a senior and military discount, a discount for college students, and a discounted rate for children under twelve. Suppose you, your friends, or your kids would have a blast checking out various ecosystems and interacting with the animals there on a deeper level than most zoos or aquariums. In that case, you should check out SeaQuest Folsom.

5. Seymour Marine Discovery Center

Santa Cruz, California

Located in sunny Santa Cruz, California, the Seymour Marine Discovery Center is another candidate for the best aquarium in California and is a community-supported marine science education center associated with the University of California at Santa Cruz (UCSC). You’ll be greeted by a giant blue whale skeleton named Ms. Blue and several life-sized elephant seal sculptures. You’ll be shocked by how enormous they really are!

One of the exhibits is Photos from the Field, a gallery of images captured by UCSC researchers in Monterey Bay. You’ll get to see photos of real wild whales, octopuses, sharks, and so much more. Of course, there are also several live animals on display, including eels and a touch tank full of friendly starfish. There’s even a nice shark swimming around who will let you pet him if you’re willing to stick your hand in his tank.

While the two aquariums we covered for Northern Cali are primarily indoor facilities, the Seymour Marine Discovery Center has only a few displays inside. Their most exciting exhibit is the great outdoors itself. They lead ninety-minute guided tours through the Younger Lagoon Reserve, a wildlife reservation adjacent to the discovery center. On this tour, visitors learn about the care of one of California’s rare coastal lagoons and about how the researchers track land and sea animals to discover more about them.

The great thing about these tours is that they are free, making this the best aquarium in California for visitors on a budget. If you’re planning a vacation on a limited budget, or a staycation near Santa Cruz, you should definitely visit the Seymour Marine Discovery Center; it’s informative, engaging, and inexpensive.

Monterey Bay Aquarium

6. Monterey Bay Aquarium

Monterey, California

The mission of the Monterey Bay Aquarium is to inspire and encourage the conservation of the ocean. And they do precisely that with their fascinating aquarium displays. Visit their deep-sea exhibit, kelp forest display, open waters exhibit, beaches and dune display, and many more to learn about the type of wildlife and ocean life that inhabit these natural places.

They also have one of the most incredible sea otter exhibits in the United States – making this the best aquarium in California for otter lovers – and a huge tentacle exhibit featuring octopuses and squid of the ocean.

7. Central Coast Aquarium

Avila Beach, California

Located in Avila Beach, California, and yet another candidate for the best aquarium in California, the Central Coast Aquarium welcomes more than 20,000 visitors to its tanks every year. Their mission is “to cultivate a community dedicated to ocean stewardship through education, engagement, and action,” which they do daily.

The Central Coast Aquarium is currently home to over seventy-five species of local marine life, including sea stars, decorator crabs, swell sharks, moon jellies, and a Giant Pacific Octopus. But it started as nothing more than an ocean enthusiast lecturing about marine life anywhere he could.

The aquarium’s founders, Russ and Carol Kiessig, established an organization in 1994. Russ spoke at restaurants and sometimes just outside on the street, telling people about the importance of caring for the ocean and the marine life within. The organization received 501c3 status in 1998, and an aquarium was finally completed in 2006.

From touch tanks to impressive ocean tank displays and the chance to pet a full-grown shark, there’s no shortage of interesting things for the whole family to do at the Central Coast Aquarium. You can even dissect a squid in the science lab to learn more about their anatomy and life cycle or walk across a boat exhibit to feel what it’s like to develop sea legs.

8. Aquarium of the Pacific

Long Beach, California

How about them penguins? Their penguin habitat is home to more than twenty Magellanic penguins in a special exhibit with areas you can crawl in or under to experience the penguins and their penguin shenanigans from a whole new perspective.

They also have a shark lagoon, a lorikeet forest (where you can feed the lorikeets and they will sit on your arm), a frog forest, and a sea otter exhibit, to name a few. Learn about these animals, where they come from, and the importance of doing your part to preserve the world we live in for generations to come.

9. Birch Aquarium at Scripps Institution of Oceanography

La Jolla, California

The Birch Aquarium overlooks the Pacific Ocean from nearby cliffs and houses more than sixty fish and invertebrate habitats. The species who call this aquarium home come from both the Pacific Northwest and the tropical waters around Mexico, some from even further away.

The aquarium has existed in some form for over 100 years. Established in 1905, it started with only a handful of tanks, grew over the decades, and then temporarily closed during WWII. Making this the best aquarium in California for those who love ocean life and history equally. It was reopened after the war and grew even fast. Now more than 470,000 people visit the Birch Aquarium each year.

In addition to the many ocean habitats, you can visit inside. It is a hefty additional fee, but spending an hour seeing baby seahorses, learning about the aquarium’s renowned seahorse breeding program, and finding out what goes into the complicated care of these animals in captivity, the cost is well worth it.

For another additional fee – about half the size of the sea horse tour – you can experience a tidepooling adventure. Guided tours fill up quickly and are by reservation only, so don’t miss your chance to explore these fascinating environments with a tidepool expert who can answer all your questions.
