My parents are currently here and visiting from the UK, so we decided to head on out to the DWA. If you live the in Dallas or surrounding areas it is definitely a trip I would recommend you take. Dad has trouble getting around so it was nice to know that they have 3 wheelchairs that are available on a first come first served basis. ID is all that is required no fee for chair :)
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!
