I visited Adrenaline Rush Zipline with my 2 eight year old kids. We had a blast. The staff is extremely professional and great with novices and kids. The zip lines are varied and most have you sailing high over ponds and lakes below. This was my first time zip lining and I was very nervous, but the staff really did a great job putting us at ease. Mt kids said it was the best "vacation" they've ever had and are begging to go again this summer. It's a relatively short day trip from Houston and I will definitely plan to go again.
