Seward park consists of small pebbled beaches, a larger swimming area, and forested trails, right on Lake Washington. Seward park is situated in Seattle's south end, but because it's right on Lake Washington Blvd the demographic tends to be on the more affluent side. The beaches are small, but not usually crowded. It tends towards families, but is also a great place to sit and enjoy a picnic with a date or meander arm-in-arm around the park.
