- $79 for a zipline adventure with a T-shirt ($118 value)
On hikes through Texas Hill Country, professional guides take you to five ziplines ranging from 250 to more than 2,000 feet long. The tour ends with a ride on Texas's longest zipline, where you'll jump off a 20-story cliff and glide above Lake Travis. The entire experience lasts 2.5–3 hours and makes a great gift for the adrenaline junkie in your family.
