We usually go to the pool in Seaside when our family visits, but one day the pool in Seaside was closed, so we decided to go to the Astoria Aquatic Center instead. The cost was quite a bit more, $14 for the family, but once we got inside we quickly realized it was worth the cost. This pool is very nice! There are 2 water slides, a large one for the older kids and young adults that opens later in the afternoon, and a small slide for the younger kids that's always available. There were actually 2 pools, the big main pool for laps and such, then the warm family pool that not only has the slides, but also a lazy river feature. Besides the swimming area, we also noticed a snack bar/cafe area in the lobby and a swim shop with goggles, swim diapers, etc. I definitely recommend visiting if you're in the area, you can easily spend 2 or 3 hours here and have a great time!
