There will be plenty of seaside favourites recreated in the landlocked town.
There will be a chance to climb inside a 50ft giant whale for underwater stories of mermaids and pirates; marvel at a giant lobster and slide on a giant creature of the deep.
Plus all the traditional favourites including sand, deckchairs, donkey rides, a brass quartet, magic shows and a bouncy castle.
The seaside extravaganza takes place from 11am-4pm on Sunday July 3. Most things are located in Kingsbury, but the giant whale will be in the museum gardens.
