Lakeside Amusement Park is a family-owned amusement park in Lakeside, Colorado, adjacent to Denver. Originally named White City, it was opened in 1908 as a popular amusement resort adjacent to Lake Rhoda by the Denver Tramway, making it a trolley park. The amusement park was soon sold to Denver brewer Adolph Zang. Eventually the name was changed to Lakeside Amusement Park, but the local populace kept referring to it by its original name for its glittering original display of over 100,000 lights. Today it is one of only thirteen trolley parks operating and one of the oldest amusement parks in the United States, and the oldest still running in Colorado. The park, comprising nearly half of the Town of Lakeside that it was responsible for creating in 1907, features the landmark Tower of Jewels.
