Since 1890, Trimper’s Rides of Ocean City is the oldest continuously family owned and operated amusement park in the world. Our mission at Trimper’s Rides of OC is to create action packed family fun. Spend your night wandering the whirling, blinking, raucous, neon-lit fun fest that is the boardwalk. Ride the Tidal Wave roller coaster, crash bumper cars, and bop Whac-A-Moles at Trimper’s!
