We live north of Dallas, and decided to make a day out of taking the DART train to the Dallas World Aquarium. Everything about our trip was great,. My kids, 3 and 7 years old, and I took the Green Line to the West End Station and walked to the aquarium, which is only about 3 blocks away. We always enjoy the Dallas World Aqaurium because it has so much more than any other aquarium around here--it is an indoor rainforest habitat with all the attractions of a regular aquarium. Both of my kids love trying to find birds and monkeys hiding in the trees, the otters, the bats, the huge shark tank, the penguins and all the smaller individual aquariums. After your visit you can walk about 2 blocks west and find all kinds of places to eat and then take the train home. My 3 year old fell asleep on the train about halfway home.
