Giant Dipper, Wooden roller coaster at Mission Beach, San Diego, United States

The Giant Dipper is a wooden roller coaster at the northeast corner of Belmont Park, occupying an irregular area about 100 by 500 feet. Its 2,800-foot track has two 75-foot hills at opposite ends, and a sign reading "Belmont" is fixed to the wooden trestle at the northeast edge.

This wooden coaster was built in 1925 and survived decades of changes in the entertainment industry. It gained National Historic Landmark status in 1987 and was recognized as one of the few remaining relics from the amusement park's early era.

The coaster's name changed with the park: it opened as Giant Dipper, ran as Roller Coaster from the 1950s to July 1976, and briefly as Earthquake until December 1976. The park itself was renamed Belmont Park in 1954 by leaseholder Jack Ray, after a park in Montreal.

The roller coaster sits along Mission Boulevard in Belmont Park and is accessible during park hours. Visitors should expect warm, sunny conditions typical of the beach area and dress accordingly for extended outdoor time.

In 1998 a local radio station, Star 100.7, ran a second riding marathon after the 1997 event; winners split $50,000 in cash prizes after 70 days on the coaster. The 1997 marathon lasted 11 consecutive days of more than 12 hours riding per day.
