This park is lovely, complete with a nice beach offering views of Whidbey Island in the distance to the east across Admiralty Inlet, the entrance to Puget Sound. On a clear day, you can see Mount Baker. It is small, quiet, and not a popular option for large gatherings, making it a peaceful spot to enjoy a short morning or evening run.

Founded in 1870 by Samuel Hadlock, Port Hadlock's history is rooted in the timber industry. Hadlock contracted with the Washington Mill Company to construct a sawmill on a spit of land at the south end of Port Townsend Bay, where the deep waters were suitable for tall ships. This endeavor resulted in the establishment of a significant lumber mill. While much has changed since then, two structures from that era still stand in town today.
