New to Westfield. Not New to Adventure.
TreeRunner has been getting people into the trees for more than a decade.
TreeRunner began in 2014 with a belief that outdoor recreation can do more than fill an afternoon. Give someone the right challenge, and you get to watch confidence grow in real time.
Today, TreeRunner operates five aerial adventure parks across three states. Grand Park brings that experience to Westfield in a location unlike any other — right in the middle of one of the country's most active sports campuses.
You don't have to arrive fearless.
You just have to be willing to try.
Why TreeRunner?
The best part isn't the height. It's what happens because of it.
Yes, there are ziplines. There are suspended bridges, nets, swinging obstacles and moments when you look down and remember you're well above the ground.
But the part people tend to remember is the challenge: deciding to keep going, figuring out the obstacle in front of them and hearing someone behind them say, “You've got this.”
That's why TreeRunner works for families, friends, athletes, schools and teams. Everyone can experience the same park while taking on a challenge that feels personal to them.
TreeRunner Grand Park
Built so you can start comfortable — then decide how far you want to go.
Grand Park's Aerial Forest includes eight trails across four difficulty levels, giving new climbers room to learn and returning climbers somewhere to push themselves.
Four Difficulty Levels
Start on introductory terrain and work your way toward more demanding challenges when you're ready.
Ages 7+
Families can experience the park together, with trail access and accompaniment requirements based on age and participation guidelines.
Choose Your Experience
Pick a 2-hour Starter climb or spend more time exploring with the 3-hour Classic experience.
Never Done This Before?
Good. A lot of our favorite climbers haven't either.
You don't need climbing experience to come to TreeRunner. Every climber learns how the equipment works before entering the aerial trails, and Grand Park has four introductory Yellow trails where newer climbers can build confidence before deciding what comes next.
What Exactly Is an Aerial Adventure Park?
Think obstacle course. Put it in the trees.
An aerial adventure park is a network of elevated platforms connected by obstacles and ziplines. Climbers move through the courses at their own pace, choosing trails appropriate for their age and challenge level.
Instead of one linear ride where everyone has the same experience, TreeRunner gives you choices. One person may spend the day building confidence on introductory trails while someone else keeps moving toward harder terrain.

Experience Matters
Adventure works better when the fundamentals are taken seriously.
TreeRunner has spent more than a decade building and operating aerial adventure parks. That experience shapes how our courses, equipment, orientations and park operations work today.
01
Orientation Before Climbing
Before entering the aerial trails, climbers receive instruction on the equipment and how to move through the course system.
02
Continuous Belay System
Grand Park uses a self-guided continuous belay system designed so climbers can move independently through eligible aerial courses.
03
Industry Standards
TreeRunner's aerial park operations are informed by established challenge-course standards, including standards associated with ACCT and ASTM.
Why Grand Park?
Because a sports campus should have more than one way to challenge yourself.
TreeRunner sits right inside Grand Park Sports Campus in Westfield, surrounded by tournaments, practices, athletes and families from across the region.
Come specifically to climb, add TreeRunner to a tournament weekend, bring a team over between games or give the family something completely different to do while you're already on campus.

Part of the TreeRunner Family
Grand Park is new. The TreeRunner story isn't.
TreeRunner was founded by outdoor enthusiasts who wanted to create a different kind of recreation — one where people aren't just watching an experience happen. They're in it.
Since 2014, TreeRunner has grown into a network of five aerial adventure parks in Michigan, Indiana and North Carolina, each with its own setting and personality.
Grand Park is our Indiana home: eight aerial trails in the middle of Westfield's sports campus, ready for the next person who looks up at the course and wonders whether they can do it.
