South Lake Sammamish


Tucked away on the southwest end of Lake Sammamish the 403-acre South Lake Sammamish neighborhood is comprised of several smaller neighborhoods located between Lake Sammamish State Park and Timberlake Park.

In addition to Timberlake Park, one of South Lake Sammamish’s gathering places is a private 4-acre park lined with Willow, Maple and Cherry trees, walking trails, a children’s playground, 2 tennis courts, a beach front with a swim dock and roped swim area, community BBQ’s, and plenty of open grass for family play and community social events.

Annually the Easter Egg Hunt and the 4th of July parade bring the community together as well as Timberlake neighborhood’s annual National Night Out gathering.

This family-oriented neighborhood was developed in the 1970s-80s and annexed from King County by Issaquah in 2006.
