Level 4
Black
Start where you're comfortable. Then see how far you want to go.
The color of each trail tells you its general difficulty. As the colors progress, the experience gets more demanding — and the trails themselves become longer and higher.
A noticeable step up with more challenge and more time in the aerial forest.
Tough, fun and elevated higher for climbers ready for a bigger challenge.
The biggest physical challenge in the park. Hoosier Hysteria is a real workout.
You don't have to complete every color in order.
But we strongly recommend leveling up gradually, especially on a first visit. Warming up on an eligible Yellow trail before Green — or Green before Blue — gives you a chance to get comfortable before taking on a significantly harder trail. Age and climbing requirements still determine which trails each guest is eligible to use.

Meet the Trails
Eight trails. Four very different levels of challenge.
You don't need to memorize every course before you arrive. Here's the important part: where each level sits in the forest and how the experience changes as you work your way up.
Yellow • Lower Level
Start Here
Sunshine & Firefly
Sunshine
Firefly
Sunshine and Firefly are TreeRunner Grand Park's two lower Yellow trails. They keep you closer to the ground and are a great place to learn how the climbing system feels, practice moving through obstacles and build confidence before heading higher.
They're optional — you don't have to start here — but they're often the smartest place to begin if this is your first aerial park experience.
Yellow • Main Platform
Head Up
Indy 11 & Football Fun
Indy 11
Football Fun
Ready to get farther into the aerial forest? Indy 11 and Football Fun are also Yellow trails, but they begin from the main elevated platform alongside the Green trails.
You still get the approachable Yellow-level experience, only now you're doing it from the main upper section of the park.
Green • Level 2
Step It Up
Green Goblin & Forest Run
Green Goblin
Forest Run
Green is where you'll start to notice the progression. Green Goblin and Forest Run begin from the same elevated area as the upper Yellow trails, but add more challenge for climbers who are ready to move beyond the introductory level.
For many guests, Green is the perfect bridge between getting comfortable on Yellow and deciding whether they're ready to take on Joker.
Blue • Level 3
Tough + Fun
Joker
Joker
Joker takes the challenge higher. The Blue trail is tougher, longer and more demanding than the Yellow and Green trails — but it also delivers more of what experienced climbers tend to be looking for.
Expect a bigger physical challenge, longer ziplines and a trail that asks you to stay focused all the way through.
And there's no ordinary staircase waiting at the end. Joker finishes with a required TruBlue auto-belay Leap of Faith.
Black • Level 4
The Workout
Hoosier Hysteria
Hoosier Hysteria
Hoosier Hysteria is TreeRunner Grand Park's hardest aerial trail — and yes, it's a real workout.
Black takes the progression another step: greater physical demand, more time on the trail, higher elevation and the kind of challenge that makes finishing feel like an accomplishment.
Like Joker, Hoosier Hysteria finishes with the required TruBlue auto-belay Leap of Faith.
What Changes as You Level Up?
Higher
The harder trails rise above the introductory
sections of the park.
Longer
More challenging courses generally involve
more time moving through the trail.
Tougher
Obstacles demand more strength, balance,
problem solving and confidence.
More Time
Difficult trails can take longer to complete
than the introductory options.
Longer Ziplines
Progressing farther into the aerial forest
means more substantial zipline experiences.
Harder doesn't just mean harder obstacles.
The entire experience grows as you move into more challenging trail colors.
The Blue & Black Finish
The only way down is to step off.
Finish Joker or Hoosier Hysteria and there's one final challenge waiting for you.
Meet the TruBlue Leap of Faith.
Both the Blue and Black trails finish with a required TruBlue auto-belay descent.
When you reach the end, you'll connect to the system, step off the platform and let the auto-belay control your descent back toward the ground.
It's one final moment of commitment after everything you just worked through in the trees.

Where Should I Start?
Don't choose a color just because it's the hardest one you can access.
Trail eligibility and trail readiness are different things. Even confident adults often benefit from warming up on an easier trail before moving into the more demanding colors.
Our usual recommendation is simple: level up as you go.

A few things climbers usually want to know.
How many aerial trails are at TreeRunner Grand Park?
TreeRunner Grand Park has 8 aerial trails: four Yellow, two Green, one Blue and one Black.

No. Progressing Yellow to Green to Blue to Black is a recommendation rather than a required sequence. We often encourage climbers to warm up on an easier eligible trail before attempting a significantly harder level.

Sunshine and Firefly are the two lower Yellow trails. Indy 11 and Football Fun are Yellow-level trails that begin from the main elevated aerial platform.

Hoosier Hysteria is the Black trail and TreeRunner Grand Park's highest difficulty level. It is a demanding physical challenge and is available only with the Classic experience for eligible climbers.
What is Joker like?
Joker is the Blue trail. It is elevated higher than the Yellow and Green sections and provides a tougher, longer experience with longer ziplines. It finishes with a required TruBlue Leap of Faith.
What is the Leap of Faith?
Joker and Hoosier Hysteria finish with a TRUBLUE auto-belay descent. Climbers connect to the auto-belay and step from the platform to complete the trail.
Does Starter include the Black trail?
No. The Black trail is part of the Classic Full Experience and is available only to climbers who also meet the applicable climbing requirements.
How do I know which trails my child can climb?
Review the Grand Park Age & Climbing Requirements before your visit. Age, reach and adult-accompaniment rules may affect which trails a climber can use.
Do I need to be athletic to climb?
You do not need prior ropes-course experience. The different difficulty levels allow climbers to choose an eligible challenge that fits their comfort level. The harder trails become increasingly physical, with Hoosier Hysteria providing the biggest workout.
Start on Yellow. See where you end up.
With 8 aerial trails and four levels of difficulty, you don't have to decide how far you're going before you leave the ground. Start climbing, build confidence and level up when you're ready.
