Go Ape Arlington turns River Legacy Park East into a high-energy outdoor challenge. Choose aerial obstacles, rope bridges, Tarzan swings, long ziplines over the trees, axe throwing, or a forest escape-room game, with options for kids, adults, groups, and after-dark climbers. The courses are staff-supported but feel satisfyingly self-directed once you are in the canopy. Book ahead, wear closed-toe shoes, and bring the group that enjoys cheering through a tough crossing.
