As you will see from the pics there are all sorts of things to see and do, not just fish. You start at the top and loop yourself down, through a Rain forest and waterfall land. Then you get to see all the wonderful aquatic life and then make your way up to the Maya Ruins and see the Flamingos, Leopard & other wonderful wildlife. They even have Manatee's here.
So find time in your busy day and make a trip to DWA I know you will enjoy!
