Do you enjoy water sports but lack access to a kayak or a board? Not a problem! Tibbetts Beach has rentals available. Do you prefer to keep your feet or wheels on the ground?

History of Lake Sammamish State Park:

Lake Sammamish is a popular fishing spot for several Native American tribes.

When European settlers first arrived in the newly formed town of Issaquah in the mid-to-late 1800s, they quickly developed the area along the lake’s southern shoreline that is now Sammamish State Park for farming. The Anderson farm, which was established in the late 1870s, was located north of the park’s small soccer fields on its eastern edge. For many years, John and Addie Anderson ran a successful dairy farm on 210 acres before passing the property on to their children. At one point, their farm supplied roughly one-third of the milk produced in Squak Valley.

Another dairy farm built by Albert Giese in 1898 was located to the east of East Lake Sammamish Parkway, near the park’s boat launch and group camp. Hans Jensen bought the farm in 1952 and left it to the state five years later.

The State of Washington purchased the first 40 acres of the park from the descendants of John and Addie Anderson in 1950. The following year, the remaining 170 acres of the former Anderson farm were purchased. The Gunderson farm was quickly purchased to provide more land and an access road.

The park was officially opened to the public on July 27, 1952. The park quickly became popular among Issaquah and surrounding community residents as a place to swim and have group picnics.
