Is it safe?
The safety and security of our guests is a top priority at RYZE Adventure Park. Our Adventure Tower uses  the  smart belay system, a technology designed for each climber to engage carabiners at the entrance of the tower stairs that will not unclip fully until the climber has returned to the bottom level of the stairs.  

While there are inherent risks in outdoor recreational activities and extreme sports, we provide guests with the instructional skills training they need to safely engage in activities. Additionally, we have signage throughout the park to direct your safe adventure and our trained RYZE guides are stationed throughout the park to assist and monitor your experience.

How difficult is the course?
Our Adventure Tower creates a safe interactive atmosphere that features 4 levels and 100+ challenge elements that range from very easy to extremely difficult. Our course uniquely allows you to pick and choose your desired route. You decide how high you go and how hard you want to course to be.

No. The Adventure Park is free for those accompanying a paid guest. Guests only pay to use the waiver-based activities at the park, such as the Adventure Tower, Observation Tower Pass, Mini-golf, etc. 
What is the cancellation Policy?
We want you to book with confidence. You can cancel your own reservation anytime before the start of your first activity. We will immediately email you the full value of your purchase in the form of a digital gift card. You may apply it anytime towards a new activity date and time.

What happens if it rains?
The Adventure Park is open rain or shine, so we recommend dressing for the weather! If you don’t want to climb in the rain, you may always reschedule for a later time in the day or for a different day even if we remain open.

We do monitor for lightning, heavy rain, high winds, snow and ice, and will close the course as necessary to keep our guests and staff safe.
