Just came for the first time. How can you not give this place five stars? Only thing I'd change is the hours. It should stay open for at least an extra hour :) ...Make sure to get there early or you won't fully soak in the diversity it has to offer. The California Academy of Sciences satisfys the curious minds of any budding environmental scientist. See More

The greatest learning place for all ages in northern California. It is a delight to find the blue morpho butterflies landing on your head. It's hands on science institute. Go up to the roof to see what we need to do in the future. Great learning place.

We went for my best friend's birthday. We had I blast brought my whole family. On our way home we all talked about what was our favorite thing. We liked our lunch. But it was weird because the workers were trying to take my tray before I had finished my lunch.

Really loved the experiences that were available there. A trip through the rainforest was great seeing all of the different creatures. Just wish there were more... guides to give information and watch patrons as there are birds and butterflies flying about. The aquariums were also informative and gave a great insight into ocean life. See More

With the war on science going on in our nation I was proud to show my support by visiting the academy of sciences. The first time since they remodeled. I worke...d there in the 90s and loved it.
Just a fantastic experience and so humbling. The new planetarium is mind blowing and a bit overwhelming. But still fantastic!
Go science!

An amazing place to visit. The rainforest and planetarium shows are a MUST see! Along with the Earthquake, color of life, and aquarium exhibits. This was our first time there, family with young adults and everyone enjoyed their time there. Definitely recommend it!

The aquarium is huge, jaw-dropping and extremely beautiful. Same goes for the globe-shaped tropical forest greenhouse/butterfly house right in the middle of the museum. The rest of the exhibits pale in comparison, however—the only thing keeping me from giving a 5.

I love Cal Academy! Great exhibits and planetary shows. My boyfriend has lived up here his whole life and this was his first time going. This was my first time seeing the penguin feeding so there was a little bit of a first for each of us!

The best! We always have a wonderful time and love the penguins and all the fish. We also love the play areas outside. So peaceful and invigorating at once.

This place is truly amazing. Bridging science and fun is the best way to educate the masses about our remarkable planet. Great layout, wonderful exhibits, and something special for everyone who has the opportunity to visit. Keep up the good work!

We love the cal academy... minus the food. They use to offer delicious & healthy food choices such as stews and polenta, tacos, fish and chips.. now the food tastes like microwaveable or frozen foods:(

So much to see, very well laid out, super interesting exhibits. Went with my niece from Germany and she wants to spend an entire day there next year, when she comes back. So that's what we'll do.

Love NightLife. Wish I could go every Thursday, but alas, I am not a richy richer, so I go when I can. Definitely love going to this place to get my drink on and stare at jellyfish for hours on end.

Too expensive for the poor. Not everyone is able to wait in long lines on free days. Should be free or not more than $5.00 adult admission.

This has been a fifth grade field trip two years in a row. It is an excellent trip for the students, there is information for all the different students' interests. It is a fun, exciting and happy learning experience for students of all levels of science knowledge.

What a great place, I brought my wife and 3 years old daughter and we all were super excited. We definitely will come back again and again
