Interlaken Park is a 51.7-acre (209,000 m2) park in Seattle, Washington. A heavily wooded hillside and ravine, it forms the division between Capitol Hill to the south and Montlake to the north. Interlaken Drive E. runs through the park north to south, and E. Interlaken Boulevard, part of which is now closed to traffic, does so northwest to southeast. Louisa Boren Park, once part of Interlaken Park, lies directly south.
History In the 1890s, Interlaken Boulevard was the principal bike and buggy path linking Capitol Hill with the boulevards on Lake Washington. The conversion around that time of the high bicycle wheel to the low bicycle wheel made bicycles much easier to ride and very popular. Assistant City Engineer George F. Cotterill, conscious of the hazards of biking on city streets lined with planks, toured the city to look for good bikeways. His bike trails formed the basis of the city’s boulevard system, and in 1903, the Olmsted Brothers approved Interlaken as a boulevard route. It soon became popular with walkers and auto drivers, who appreciated the views of mountains and lakes. In 1913, five acres of the Interlaken area were set aside as Louisa Boren Park to honor Louisa Boren Denny, the last surviving member of the party of pioneers that landed at Alki in 1851.
