Officials at the Chula Vista Resort in the Wisconsin Dells say they will be offering the nation’s longest head-first racing zipline this summer. They hope to open the course to the public by Memorial Day. People on the “Soar Like an Eagle” course at Dells Zipline Adventures fly “superhero-style” down nearly two-thousand feet of parallel ziplines into the forested areas along the Wisconsin River. Racers fly prone, 100 feet in the air. Officials say Dells Zipline Adventures offers experiences for participants at all age and skill levels. There are 18 ziplines and four aerial rope courses located there.
