Neat old naval fort on Puget Sound.
Extremely cute cidery in nearby Chimacum
Port Townsend is a fantastic place to see the amazing wildlife in the Pacific Northwest. If you're looking for something to do the morning of the wedding, the half-day trip will get you back just in time for the ceremony.
If you are looking for a day trip in the Port Townsend area, Olympic National Park is a must-see. It's about a 1.5-3 hour drive from PT to most areas of the park. David and Emily recommend checking out the Hall of Mosses, Ozette Triangle, and Rialto Beach if you decide to make the trip out! Keep in mind that there are no roads that cross the park, so good transportation planning is a must.
