Old school pinball, beer, air hockey and museum: the perfect combination of amusements come together on the mezzanine overlooking Neptune’s Kingdom at the Santa Cruz Beach Boardwalk. Neptune’s Kingdom is a pirate-themed miniature golf course in the historic natatorium on the boardwalk. Play air hockey with your friends, drink a beer, and browse exhibits and photos on the Plunge, the huge indoor pool that used to fill the building. Historic arcade games are also on display. The Historium is less crowded than the rest of the boardwalk, and probably more fun than waiting in line for rides outside.
