The Seattle Aquarium is a popular destination for tourists and locals alike. This iconic waterfront landmark is a must-see, particularly for families with children, although it's a great place to visit for anyone who wants to get a fascinating look at the area's spectacular underwater world. With its wide array of colorful marine creatures in award-winning exhibits and touch pools, guests of all ages and tastes are sure to find something to enjoy. One of the best ways to enhance your visit is to check out the host of sea life that can be found in the Pacific Northwest at the aquarium, and then head out on an adventure to see what you can find in the Puget Sound waters or in the tide pools along the state's breathtaking, rugged coastline.Parking and public transportationThe aquarium is easy to get to by car or public transportation, located on Pier 50 on the downtown central waterfront. Inexpensive metered parking is available right across the street below the Alaskan Way viaduct. Metro Transit offers many bus routes that will bring you within a short walk of the aquarium, including Route 99, which stops directly in front of the building.Best and worst time to go to the Seattle AquariumThe Seattle Aquarium is open every day of the year except Christmas Day at 9:30 a.m., with the last entry accepted at 5 p.m. and exhibits closing up at 6 p.m. The best time to get here is just after 2 p.m., when the crowds typically begin to thin out whether it's on the weekend or a weekday. Most visitors tend to arrive shortly after the aquarium opens, making it more difficult to get good views of the exhibits without having to bump elbows with others, particularly during the months of June, July and August.Admission to the Seattle AquariumAdmission to the aquarium ranges from about $15 to $22 depending on age with children three years old and under admitted free. Discounts are available for seniors, persons with disabilities and active military.Must-Dos at Seattle AquariumTouching some of the fascinating creatures that live in the tide pools on the state's outer coast and the inland sea of the Puget Sound is a must.
