I like Lahinch Seaworld. They have an amazing pool that includes a great pool for just kids. The aquarium end of things might not be as great as it could, but it's a good start. They also have an activity centre where they have various classes and what not but I personally have never taken part in those. I just enjoy taking my son to swim here after a day at the beach. One thing to note, check the website and ring ahead before visiting because they only have public pool hours on certain days at certain times and the aquarium is only open on certain days at certain times. read more
