Aquariums
There are two Aquariums to choose from, or you can just visit both while you’re at it. Depending on which side of Istanbul you are staying on (European side for Istanbul Aquarium, Asian ide for ViaSea Aquarium) you might opt for one of both. Both are mesmerizing, and will have you feeling “under the sea” The Istanbul aquarium will surely leave the kids in awe with its line-up of piranhas, sharks, penguins and more. The ViaSea Aquarium is a little more extensive, boasting over 12000 sea creatures, and kids can even partake in feeding sessions and daily tours. Of course you also have rollercoasters to top the whole thing off (28 to be exact)
