Lake Travis Zipline Adventures at Lake Travis, Texas, US, has launched a new single line "Double Barrel Shotgun" tour option for the summer and autumn season.

The tour takes an hour and a half tour and takes guests soaring over Lake Travis on the longest and fastest zipline in Texas.
Available only Friday to Sunday, the tour will feature the 2,800ft long Double Barrel Shotgun zipline. Costing US$84, the guided tour includes a traditional boat ride, an approximately one-mile-long nature hike, beautiful lake views and, as with the full excursion, all-day access to Adventure Island. For a limited time, all single line guests will also go home with a photocard containing photos from their tour at no cost.
Located at Adventure Island, Lake Travis Zipline Adventures is known for its traditional three-hour guided adventure with five of the fastest and longest ziplines in Texas, ranging from 300ft to over 2,800ft.
Each adventure includes all necessary equipment, boat transportation and bottled water throughout the tour, with additional all-day access to a private lake front property where adventurers can picnic, play games, or relax in one of the hammocks. Reservations are required.
