Aquário da Madeira is a small aquarium located in Porto Moniz, Madeira. It offers visitors the chance to see a variety of sea creatures, including sharks, rays, and other fish species. While some visitors find it fascinating to get up close with the marine life, others feel that the tanks are too small and the displays lack variety. The highlight for many is the opportunity to dive in the aquarium's large tank, which can be a unique experience for those looking for something different to do in the area. Overall, it's a mixed bag - some love it, some think it's not worth the visit.
