Do This Before You Arrive
Get the waiver out of the way now.
Each climber needs a waiver before entering the Aerial Forest. A parent or legal guardian must complete the waiver for participants under 18. Guests age 18 and older complete their own. Non-climbing spectators do not need a climbing waiver.
Completing waivers in advance helps keep your reservation moving when you arrive.
Can I Climb?
Check the participation requirements before booking.
Aerial Forest access depends on age and physical participation requirements. Which trails you can use may also vary by age.

Maximum Height
60–265 lbs
Standard Participant Weight Range
Climbers under 60 lbs may still climb when
accompanied by an adult.
Some climbers may participate with adult assistance.
A shorter reach or a weight below 60 lbs does not automatically prevent participation. Climbers under 60 lbs may climb with an adult, and guests who cannot reach 6 feet may need a parent or accompanying adult to assist with transfers. Additional adult-accompaniment requirements may also apply based on age and course difficulty.
What to Wear
Dress for moving through the trees.
You don't need special climbing clothes. You do need footwear and clothing that work with a harness and outdoor movement.
Closed-Toe, Closed-Heel Shoes
Athletic-style footwear is required. Sandals, slides and open-backed shoes won't work for aerial climbing.
Climbing Gloves
Gloves are required in the Aerial Forest. Bring your own suitable gloves or purchase them at the park.
Comfortable Clothing
Wear clothing that lets you bend, climb and move comfortably while wearing a harness around your shoulders and legs.
Dress for the Weather
Layers work well in cooler temperatures. TreeRunner can operate in rain, so rain gear is useful when showers are possible.
Tie Back Long Hair
Long hair should be secured before climbing. Avoid dangling jewelry and loose accessories.
Expect to Warm Up
Climbing is active. On cooler days, dress in layers you can comfortably move in as your body temperature changes.

First-Visit FAQs
Still wondering about something?
Do I need climbing experience?
No. First-time climbers are common at TreeRunner. You'll learn how to use the equipment before entering the aerial trails.
Does everyone who comes to the park need a waiver?
Climbers need a completed waiver. Non-climbing spectators do not need a climbing waiver simply to accompany your group.
Who completes the waiver for a child?
Participants under age 18 need the appropriate waiver completed by a parent or legal guardian. Adults age 18 and older complete their own waiver.
Can someone under 60 pounds climb?
Yes. Climbers under 60 lbs may still participate when climbing with an adult. The standard participant weight range is 60–265 lbs, but being under 60 lbs does not automatically prevent a guest from climbing.
Can I climb if I can't reach 6 feet?
Potentially. Six feet is the reach guideline for transferring independently. Guests with a shorter reach may still participate when a parent or accompanying adult can assist with transfers, subject to TreeRunner's participation requirements.
Are gloves required?
Yes. Gloves are required in the Aerial Forest. You may bring suitable gloves from home or purchase them when you arrive.
What kind of shoes can I wear?
Closed-toe, closed-heel athletic-style footwear is required for Aerial Forest climbing.
What if it rains?
TreeRunner can operate in rain, so a rainy forecast does not automatically mean the park will close. Certain weather conditions can suspend or affect climbing. Review our Weather & Rain Policy for current details.
Where exactly is TreeRunner inside Grand Park?
Guests entering from 186th Street should head toward Lot G. Guests entering from 191st Street may use Lot D. See our Directions & Parking page for the campus map and full route details.
Should I choose the 2-hour or 3-hour climb?
Starter is a good shorter option and works well for many first-time climbers. Classic gives you an additional hour, access to the Black course for eligible climbers and access to the Bypass Quiz.
What is the Bypass Quiz?
The Bypass Quiz is an optional TreeRunner program available through eligible Classic visits. Review the Bypass Quiz information for current details.
Still Have a Question?
