Zoomarine (shows with dolpins, sealions parrots, an aquarium and childrens' rides) can be found on the main road between Albufeira and Lagoa (you will pass it on the road from the airport). You can also swim with dolphins (need to book this).

If you want wet and wild, try the waterpark - called Slide and Splash (our son would spend all day every day here, but he doesn’t get the chance very often, as it’s rather noisy and hot) Located off the old main road before Lagoa coming from Lagos.
