George and Mary Ann Drake founded a garden and nursery in 1981, offering educational opportunities in horticulture to youth with developmental disabilities. They later opened the park to exhibits by local artists which was the beginning of the permanent collection.
In 1993, the City of Bellingham purchased the 2.5 acre garden and surrounding 11 acres of land from the Drakes.
In 1998, the City of Bellingham opened the 2.5 acre former nursery as a public sculpture garden now called Big Rock Garden Park.
In 2019, the Park received an additional four sculptures for its collection from the estate of sculptor David Marshall. The addition of these Marshall sculptures prompted the creation of the Marshall Gallery along the western side of the park.Â
Since 1998, community volunteers have been an integral part of the park's maintenance and vibrancy as Park Stewards. The current group of committed volunteers formed and registered as a non-profit in 2025 in order to better advocate for the park, raise funds and complete projects. Friends of Big Rock Garden Park continue to volunteer as Park Stewards in addition to their Friends commitments.
