About this experience partner:

Additional information:
Please contact us to book groups 8+ for the special group rate and to book ground-based team building
In order for guests to be able to reach the safety lines and manage their way through the adult course, they must be able to reach the middle of their palms to a height of 5’11″ (180 cm) while keeping their feet flat on the ground
Weight limit: it really depends on the shape of the person to know if the weight can be a problem. (E.g., a 6’5″ 275lb person can fit the harness, but a 5’2″, 275lb person probably cannot - it’s all about a proper fit, so 275 lbs. is a general limit)
Ages 12+ are permitted on the Adult Course (ages 12-15 must be accompanied by an adult at a ratio of 1 adult per 3 teens)

Frequently Asked Questions
What are the basic safety rules?
We have a number of safety rules. #1) Always be clipped in. You must always be clipped into the safety lines and/or cables. #2) Carabiners or Clic-ITs should have their gates facing the same direction. #3) Always have your carabiners or Clic-ITs at waist height or higher. Another rule sometimes referred to as #4) Do not touch the climbing gear of other people. These are the basics but we will give you more detail and demonstrate the rules when you arrive. Remember, always be clipped in.

What is an Adventure Course?
A Tree Top Adventure Course is an adventurous obstacle course set in the natural environment where the course is located, in this case, Flagstaff, Arizona. The obstacles are suspended between trees and participants stay securely clipped on a safety cable throughout the course. The obstacles you will find in our park include suspended bridges, scramble nets, swinging logs, a skateboard, and much more! If you complete all five adult courses and 70 obstacles, you will also have been on 8 ziplines plus the short one on the Demonstration Course. So give the course a try and test your limits!
What are Adventure Ziplines?
Our Adventure Ziplines are awesome! This is an ACTIVE zipline experience unique to our Park. The Ziplines are similar in length to the ones on our Adventure Course but there are more than 30 of them! Be prepared to walk about 5 minutes to the start and between courses, but you will end up right back where you learned how to use the gear earlier in the day. The ziplines do get very high in the trees and there are a number of ladders and bridges to negotiate so you will need some physical endurance to complete all of the Zips. In addition there are a few ziplines with action elements that also lower you to the ground, so be prepared for that. And to get to them you need to go through the obstacles!
Should I make a reservation, or can I just walk up?
Booking in advance is STRONGLY recommended to avoid any delays upon your arrival. It is common for us to sell out on weekends so booking in advance assures your group is able to Play in the Trees when you want.
