Ziplines originally were invented for just two functions: sneaking hamburgers over the Berlin Wall and zazzing up presidential entrances to State of the Union addresses. Put gravity in its place with today’s Groupon to Lake Geneva Canopy Tours. Choose between the following options:

• For $42, you get a weekday canopy tour (up to a $95 value).
• For $42, you get a weekend canopy tour (up to a $95 value).

Lake Geneva Canopy Tours elevates tree trekkers 10–75 feet above the 100-acre park to zip along an aerial route surrounded by wildlife, mature forest, and tranquil trails. After gearing up, crews practice zipline techniques a few feet above the ground under the watchful eye of guides and judgmental eagles before implementing their recently honed skills on the canopy course. Nine ziplines navigate patrons across the park along with 18 platforms, five SkyBridges, three tree-based spiral stairways, and a double-helix stairway wrapped around an ash tree that holds the genetic code of Tarzan. Upon reuniting with terra firma, customers conclude their 2.5-hour eco adventure by gearing down and penning thank-you notes to hawks encountered on the expedition. Lake Geneva Canopy Tours begins its daily sessions at 8 a.m. and sends its last group skyward at 3 p.m.
