XDrenaline, Marietta

At XDrenaline, rock climbing is even more intense than it is on a real rock face. The struggle to find footholds and handholds while rising ever further from solid ground—that's all still here. When climbers look straight ahead, though, they just might gaze at something even scarier than heights: the eyes of a fellow climber. Designed to allow climbers to see each other during competitive races, the family fun center's rock-climbing wall is fully transparent, with footholds and handholds on either sides—making for an exhilarating experience that reminds climbers they're not alone in conquering the wall.

Climbing isn't the only way to defy gravity at XDrenaline. Guests can also bounce on wall-to-wall trampolines in bright blue and chartreuse, occasionally somersaulting into a cushy foam pit, or also use the trampolines for games of bouncy dodgeball. Other options include swinging for the fenced-in fences in the batting cages or burning imagined rubber while singing "Greased Lightning" in the drag-racing simulator.
