Manhattan Beach, which was located on the shore of Sloan’s Lake, opened as a summer resort in 1890 and transformed into a true amusement park before its demise in 1914. Manhattan Beach was home to Denver’s first roller coaster and merry-go-round, a steamboat that cruised Sloan’s Lake, and dozens of other amusements during its short existence. Although it’s been gone for more than a century, the park is still remembered for both a tragedy and its role in Denver’s amusement park history.
