I should start out by stating that all aquariums have a critical flaw, in my opinion. And that is this: you have huge crowds in a necessarily enclosed space all trying to look through the equivalent of a window. It is almost certain to result in pushing, crowding, and a miserable experience (for me at least).
The Lisbon aquarium is no different. Rather than focusing on how stuffy, overcrowded, and potentially germ-ridden (hello tons of grabby children) the place was, I'll try to keep this positive and focus on the good things.
First off, the aquarium is very well curated. The central, very large exhibit is wonderful. I'd never seen a sunfish and I'd never seen a tank large enough to result in fish schooling. It was magical. I felt like I was watching a scene from "Finding Nemo." I loved that part.
The directional flow of guests is also very cleverly done. I like starting at the top of the facility and being directed circularly down to the lower level while moving through different "environments."
So, on those fronts, this aquarium is certainly above average. The temporary exhibit while I was visiting was the "Submerged Forest." I found it very nice. I like how, at first, it looked like there was no life, but upon closer inspection, the vegetation was alive with small fish. The addition of seating and music created a lovely experience.
Overall, if you're prepared to be sweaty, touched by a lot of children, and forced to squeeze next to strangers to oogle at the windows, I would recommend it.
