About Downtown Aquarium Houston
Downtown Aquarium Houston mixes a 500,000-gallon aquarium with a small ride park and a seafood restaurant in the middle of downtown. It works well for young kids and rainy days. The All-Day Adventure Pass covers the exhibits and the rides, and the $49.99 Weekend Adventure Pass is the better buy if you will also hit Kemah or Galveston.
