It’s a small, cute aquarium, not one of those huge, super dramatic ones. The place isn’t very big, so you can probably see everything in a little over an hour. Great for a casual stop if you’re already in the area.

Overall, it has a very simple, local feel. It’s not one of those newest, super flashy aquariums, but it’s really easy and relaxing to visit. The aquarium isn’t large, so you can see everything in about an hour. It fits nicely into a gap in your itinerary.
