This is one of the best Sealife centres i have been too. Its located right on great yarmouth beach and pay and display parking is available close by.
Its very pricey to get in but most sealife centres are.
When you pay they will stamp your hand and allow you to come in as many times as you like that day.

The center does alot of talks during the day they include the rays and the sharks.
You can watching a turtle feeding sesion or if your lucky enough to be about the sharks feed but they only do the sharks once a day.

The centre opens at 10am and the last admission is a four.
It costs £30 for a family booking online out of season but it is much more expensive on the door, you can usually get money off vouchers easily just check ebay.

There is normally a member of staff with a rock pool doing a demonstration it's called the touch pool encounter containing crabs starfish and anemones that you can touch and feel, something my 2 year loved and my son who loves animals was very interested in.., they will tell you all about them.
As you leave there is a massive gift shop that sells everything from clothes, ornaments, toys, and books, all of which can be pricey but good to have a look around.
We got a sharks tooth for £2 which my son loves.
Kids love these sort of places and its a great morning or afternoon out!
