Allyn Allyn overlooks the shoreline of North Bay-Case Inlet on Puget Sound. The Village of Allyn features the beautiful Allyn Waterfront Park and Gazebo,a vision that became a reality in 1986. Members of the ACA raised funds and provided much of the labor for its construction. The gazebo is used for town celebrations, weddings, concerts and picnics. It is open to the public every day. Boat launch and moorage facilities are available at the Allyn Pier, owned and operated by the Port of Allyn. Allyn is designated as an Urban Growth Area, with plans for the town’s future development well underway. The village offers a shopping center, three restaurants, a market and several small shops.
