1. Six Flags Over Texas
What is it? The crème de la crème of Texas theme parks is located in Arlington, halfway between Dallas and Fort Worth.
Why go? Adults and kiddos alike will have a blast at Six Flags Over Texas, a 212-acre wonderland with towering roller coasters and plenty of family-friendly rides and attractions. Just a couple of pro-tips to keep in mind: If you want to take advantage of potential discounts, be sure to call Six Flags before visiting; also, to avoid long lines, plan to visit the park in April or September, when attendance is lightest.
