There is no 38th Street County Park in the state of California. However, there are several parks with similar names, such as 38th Avenue Park and 38th Street Park, both located in Los Angeles.

38th Avenue Park is a small park that features a playground, basketball court, and picnic area. It is a good place for families with young children to relax and play.

38th Street Park is a larger park that offers more amenities, including a baseball field, basketball court, tennis court, and volleyball court. It also features a playground and picnic area.

Both parks are located in urban areas and can be busy, especially on weekends. They are open year-round and can be visited at any time, but the best time to go is during the spring and fall when the weather is mild.

Overall, while these parks may not be major tourist attractions, they can be great places for locals to enjoy some outdoor recreation and relaxation.
