Clarke Beach Park is a serene 9-acre waterfront park located on the east side of Mercer Island, Washington. It was once home to the Girl Scouts' Camp Tarywood and was developed in 1971. The park features fishing and swimming piers, an enclosed swimming area, picnic tables, paved walkways, and open natural spaces. It is known for being the quietest waterfront on Mercer Island, with fewer sunbathers and swimmers compared to other beaches. The park loses sunlight earlier than west-side parks, making it more popular for dog walkers and those seeking a peaceful atmosphere.
The park's natural areas have been restored through volunteer efforts, focusing on removing invasive species and planting native trees and shrubs. This ongoing restoration enhances the park's natural beauty and wildlife habitat.
Clarke Beach Park is accessible via a steep, paved trail from the parking lot off East Mercer Way, offering a tranquil escape from the bustling city life.
