Men, women, and children walk through the 100 acres of trees at Lake Geneva Canopy Tours every day of the year, but this isn't as ordinary an occurrence as it sounds. For one, much of the journey takes place 10–75 feet above the forest floor, where serene views stretch in every direction.

Amid the canopies, guides lead their groups on an eco-adventure, during which they soar across eight different zip-lines, climb over five sky bridges, and ascend three spiral staircases. The treetop trek ends in high-speed fashion, as a 1,200-foot dual racing zipline takes its riders soaring to the course's finish, though not to the end of their time in the forest. That's because there's still a high-ropes course with 18 challenges to conquer, and also because every visitor gets a same-day Arbor Trails Pass to explore the area by foot, bike, or successive cartwheels.
