The Poulsbo Marine Science Center is free and open Thursday-Sunday (11am - 4pm). Please visit and donate some money because this place was wonderful. The volunteers were helpful and had a multitude of interesting information. My 3 year old spent 2+ hours here and did not want to leave. They have a touch pool and other tanks with local marine life. Additionally, the craft room in the back should not be missed. Also the movie about the local waters and sea life was well done. If you are in the area this place is highly recommended for both kids and adults.
