You've come to know AVA's exceptional experiences and world-class adventures on the river and the rock. But now you can experience another one of Colorado's most exciting adventures with us too: zipline tours! AVA is proud to have the only zipline tour in the Upper Arkansas Valley. Located on our 44-acre outpost between Buena Vista and Leadville, the course allows you to blast among the treetops with some of the most amazing views you can imagine. You'll come to our Granite Outpost for your zipline tour. To get to the first zip requires a hike of approximately 10 minutes. And then it's all downhill! Travel over 3,000 feet through the pine and aspens of our mountain property. Look down upon the Arkansas River and surrounding peaks as you get one of the thrills of a lifetime! Follow (or start) your zipline tour with one of our amazing Arkansas River rafting trips. The Colorado white water rafting trips on the Arkansas River are known as some of the very best in the world! We have fantastic rafting/zipline packages to save you money and help you cram the most adventure possible into a day!
