The Monterey Bay Aquarium is built on the site of an old sardine cannery, right at the edge of the Pacific, and its genius is that almost everything it shows lives in the bay out front: sea otters, jellies, sharks, a forest of giant kelp swaying with real waves pumped in from the sea. It's about two hours south of San Francisco, on California's Central Coast, and one of the most respected aquariums in the world. Here are Monterey Bay Aquarium ticket prices as of November 11, 2026, the hours, how to get there and how to make the most of your visit.

When is the Monterey Bay Aquarium free?
It's one of the most common questions, so let's be clear: there are no free days for the general public. Children 4 and under are always free. There's also a program, Museums for All, that gives free admission to holders of a US food-assistance (EBT) card and up to three guests, designed for low-income residents; it doesn't apply to international tourists.
If you want to see it without paying, the aquarium runs free live cams on its website of the otters, the jellies and the kelp forest. They don't replace a visit, but they're a great preview for kids.
From sardine cannery to aquarium
In the early 20th century Monterey lived on sardines. Cannery Row was a line of canneries that reeked of fish day and night, until in the late 1940s the sardines vanished from the bay through overfishing and the plants closed one after another. The aquarium opened in October 1984 in the building of one of them, the former Hovden Cannery, with the backing of the Packard family, of Hewlett-Packard fame. Inside you can still see boilers and parts of the original plant.
Since then the aquarium has become a center for research and conservation. It created Seafood Watch, the guide that recommends which fish and seafood to buy based on how they're caught or farmed, and its program for rescued otters helped show how to return orphaned pups to the wild. Knowing that changes how you look at the tanks: it isn't an amusement park with fish but a window onto the bay across the street.
What to see inside
The aquarium is large and split into two wings. What nobody should skip:
- The Kelp Forest. A three-story tank where giant kelp sways with the swell and sardines, rockfish and leopard sharks swim. It was one of the first in the world to keep live kelp in an aquarium.
- The sea otters. The stars. Many were rescued as pups and can't return to the ocean. Feeding times are in the day's program; check it when you arrive.
- Open Sea, the open-ocean gallery, with an enormous window onto a tank where tuna, sharks, rays and sea turtles glide past.
- The jellies, in dark rooms with colored light. The most photogenic section and the most calming.
- The tide pool deck, outdoors over the bay, where you sometimes spot wild otters, harbor seals and sea lions.
There are touch pools where kids can feel sea stars and anemones with help from volunteers. Behind-the-scenes guided tours are also sold, for $29 to $40 on top of admission.
How to get there from San Francisco
Monterey is about 190 kilometers (120 miles) south of San Francisco. Your options:
- By car. About two hours via Highway 101, then 156 and 1, without traffic. It's the most convenient and lets you continue down the coast to Carmel and Big Sur.
- Along the coast. Highway 1 from San Francisco, through Half Moon Bay and Santa Cruz, takes about three hours, but the scenery justifies it if you're not in a hurry.
- Without a car. You can combine train and bus via Salinas or San Jose, but it's slow. For a day trip, tours from San Francisco are more practical.
In Monterey, parking near Cannery Row is paid, with public garages a few blocks away. If you stay in Monterey, the area is walkable.
How to plan the day
Arrive at opening. The first hours are quietest, and on weekdays school groups arrive mid-morning. Start with Open Sea and the jellies, which fill quickly, and save the tide pools for the end, when you want fresh air.
For lunch, Cannery Row has seafood restaurants with ocean views, and the aquarium has its own restaurant. Afterward, a walk along Cannery Row, the street John Steinbeck made famous with his novel of the same name, and along the Monterey Bay Coastal Recreation Trail, a seaside path ideal for biking, rounds out the afternoon.
If you're continuing on, 17-Mile Drive and Carmel-by-the-Sea are 15 minutes away: with them you have a perfect weekend on the peninsula.
Which aquarium is best?
Among US aquariums, Monterey is in the top tier alongside Atlanta's Georgia Aquarium and Chicago's Shedd. Atlanta's is bigger and has whale sharks; Monterey's is more intimate, more scientific and sits right on the ocean it showcases. If you care about conservation and Pacific coast marine life, Monterey wins.
Monterey on a California road trip
Monterey is a natural stop on the coastal route from San Francisco to Los Angeles. Heading that way, Highway 1 continues to Big Sur, although some stretches close because of landslides; check the road status with Caltrans before you set out.
Monterey's climate is cool year-round, with morning fog in summer. Bring a jacket even if it's sunny in San Francisco.
Tips for the visit
Buy online: in high season and on long weekends, tickets sell out. Check the day's program when you arrive so you don't miss the otter or kelp forest feedings, when the animals are most active. The jelly rooms are dark; turn off your flash, which besides ruining the shot disturbs the animals. And if you're with young children, split the visit into two rounds with a meal break in between: it's a lot of stimulation for one go.
