Notes:
Aptly named park as it's right next to a large marina! Which means there could be boat traffic on a sunny day. We swam across the main entrance to the marina early on a dreary day with no problem. There is a public boat launch available. The park has a gravel beach, lawn and picnic areas, and restrooms. Part of the shoreline is a sculpture display built using large, natural boulders (note merman sitting atop one in photo gallery). The bottom is normal Lake Washington rocks.
