Markin Farms Zipline Adventures, West Liberty

A collection of adrenaline-pumping ziplines whoosh through the forest on Markin Farms Zipline Adventures’ 80-acre farm. The multilevel platforms, built high in the trees, connect the course’s ziplines, which pass above bubbling creeks, over ponds, and through time. The scenic course includes challenge areas and ends with a double-zip setup, where two riders race to the finish directly above or below one another, overlooking the sparkling water. The farm also offers specialty zips that glide through the forest after twilight or just as the sun sets.
