Lotus Isle Amusement Park opened on June 28, 1930. Known as "the Wonderland of the Pacific Northwest", was located in Portland, Oregon, just off the east tip of Hayden Island. Lotus Isle was located just east of the more successful Jantzen Beach amusement park. Lotus Isle spread out over 128 acres (0.52 km2) and at the time was Portland's largest amusement park.
Lotus Isle Amusement Park opened on June 28, 1930 after a group of investors realized the success of the nearby Jantzen Beach Amusement Park. At the time of its opening, Lotus Isle was the largest amusement park in Oregon. The park consisted of forty attractions including bumper cars, a rollercoaster, and a dance hall called the Peacock Ballroom.
On August 28, 1930, a sixteen-year-old boy fell from the roller coaster into the Columbia River and drowned. Edwin Platt, the park's owner, committed suicide the day after the drowning. For the following season, a promoter named Al Painter took over management of the park, and created a "Dance-A-Thon" event in the park's Peacock Ballroom, which held room for 6,600 dancers. During this time, a temperamental bull elephant named "Tusko" was sold to Lotus Isle from John Ringling. The elephant soon destroyed several pavilions after being spooked by a low-flying stunt plane, and escaped from the park before being caught in Sedro-Wooley, Washington, and taken to the Woodland Park Zoo in Seattle.
On August 24, 1931, almost a year after the drowning and Platt's suicide, the Peacock Ballroom burned to the ground. The park operated once more in the 1932 season before going into bankruptcy, after which liquidation of the park property began.
