Grand Park Live

About

TreeRunner is an aerial adventure park in the woods on the Grand Park campus: 8 aerial trails at four difficulty levels and more than 1,000 feet of ziplines, for ages 7 and up. Climbs are 2 hours (a starter climb) or 3 hours (the full classic, which opens the Black course to climbers who qualify).

It's the one thing on campus anyone can book, so it fills a gap between games. Birthday parties, school trips, teams and company outings can reserve the days it's closed to the public.

When to go

The 2026 season is nearly over: open Saturday, Nov. 14 (11 a.m. to 6 p.m.), Sunday, Nov. 15 (10 a.m. to 5 p.m.) and Saturday, Nov. 21 (11 a.m. to 6 p.m.), the last day. Fridays Nov. 13 and 20 are closed. It reopens in spring 2027; in 2026 the season began March 21.

Hours depend on the weather, so check online availability before you head over.
