Big Rock Park Central is a 20-acre park located in the heart of Sammamish. The land that makes up Big Rock Park Central includes dense forest cover, open meadows, a stream in the north, and over 1.5 miles of meandering trails that navigate through the property and connect to Big Rock Park North. The park also hosts several unique features, such as the historic Reard House, a heritage garden, and The Treehouse.

  • The Sammamish Heritage Society has led restoration work on the Reard House and is in the final stages of interior renovation work to open this historic house to the public. For more information on the history of this house, please visit the Sammamish Heritage Society webpage.
  • The Heritage Garden was built in partnership with the Sammamish Botanical Garden Society (SBGS) and is open during regular park hours. The 6,000 square foot garden was built by the City; the SBGS led the design and planting of the garden and will also lead volunteer efforts to maintain the garden.
  • The Treehouse will be open for visitors four times per month from March through October. These dates and times are posted at The Treehouse webpage and are also posted at the park kiosk.

In 2010, Mary Pigott gifted three parcels located in the center of the City (North, Central, and South) totaling 51 acres to the City of Sammamish as part of a phased land donation agreement. The first parcel, Big Rock Park North, was transferred in 2011. Following the transfer of the first parcel, the City began work on a master plan for both Big Rock Park North and Central. The master plan was adopted by City Council in 2014. Big Rock Park Central, the second of three parcels, was donated to the City in 2017. After concluding the first phase of improvements, the park opened to the community in late spring 2021. The third and final parcel will be donated in the future; it is currently the private property of Ms. Pigott.
