Top Aquariums Oceanariums in Barcelona

If you can, visit on a weekday, especially Tuesday or Wednesday. The crowds were way lighter, and I didn't feel rushed at all!

Definitely buy your tickets online! I saved time by skipping the line, which looked super long at the entrance. Plus, you can sometimes find discounts online

Check out the feeding times for the sharks and rays. I totally missed it but heard it was a highlight! I recommend marking it on your map when you get there.

Don't skip the gift shop! I found some cute and unique souvenirs there that you won't spot at other touristy spots. Just watch your budget, they can be a bit pricey.
