Amazing historical park overlooking the sea across from Whidbey Island. It is a military installated from the 1850s pretty much. Many generations and iterations of the fort. Beautiful natural surroundings. Well maintained historical areas and lodging.

Bit of a drive but a really cool place if you're into history, bunkers and the seaside. Gives you a good sense of how this seaside fortress functioned back in the day. Would love to stay in one of the cottages or homes sometime.

Another great state park for an enjoyable beach walk near Port Townsend. You can make it a 5-mile roundtrip. Park at the north end and start your loop along the stony beach, with views toward Port Townsend on one side and Whidbey Island on the other. Parking: Discover Pass required.

Really liked the view from our campsite. Very nice wide trails all over the park, a lot of them with great views. Nice boat ramp. Lots of nice beach. Flush toilets and running water. Hot shower. Only 4 stars because campground, at least the upper part, has a real mouse problem. They were running all around our site once the sun went down. Make sure to keep your food locked up good.

Bring a flashlight if you want to walk through the old military batteries. I captured three different sky photos. I considered the bathroom clean as state park bathrooms can get. A lot of people were riding electric scooters around. It seemed like a pretty quiet state park.
