Unfortunately, as an AI language model, I do not have access to the internet and cannot perform searches. However, there is a Bow Lake Park in Washington State, which is a peaceful park located in a residential area. The park features a playground, picnic tables, and a basketball court. It is a great place for families with children to enjoy a picnic and outdoor activities. The park is also relatively close to other popular attractions, including the Space Needle, Pike Place Market, and the Seattle Aquarium. In terms of the best time to visit, it is recommended to visit during the summer months when the weather is pleasant and conducive for outdoor activities.
