Pre-Opening Annual Membership FAQ

Yolanda Chen

Our pre-opening annual memberships (for both adults and youth) are now for sale at our online store! After our Facebook announcement earlier this week, we have been getting a lot of questions about our pre-opening membership special. Here is an in-depth FAQ list that will hopefully help clarify some of the questions you may have. If you have more questions, please email us at: We will try to add on to this list as more questions come in. Thank you for your continued support towards our mega project! 

What does this mean for me?  You get unlimited climbing during special pre-opening hours. Prior to the Grand Opening, all trial classes and training clinics will be free! Not only will you be able to come in and climb before the rest of Knoxville does, we'll be sending you invites to members only events before we open to the public, just to make you feel even more special. 

So when exactly can I start climbing?  NOW! We are currently in our soft opening phase and have members only climbing hours available 1-3 times a week. Get in on it and start climbing today! 

What will your pre-opening hours be?  Members only climbing hours vary week to week, depending on construction. Currently members are getting in about 1-3 times a week for climbing, classes, fitness and yoga. 

When will you be posting your pre-opening hours? Members only climbing hours are posted on a weekly basis and can be found on our events calendar. 

Will there be a way to preview the gym before buying a pre-opening membership? We have been doing sneak peek preview tours of the facility on a regular basis. Look for more tours to become available by checking back regularly on our website and Facebook page. 

Will you have climbing instruction or training sessions available during your soft opening? As a loyal and valued member, you will be invited to attend any of the trial classes or group training sessions as they become available.

Can I get top rope or lead certified during this time?  Yes, we encourage you to get your certifications done before the Grand Opening.

How much do I need to pay?  The price for our annual membership is only $599 (all memberships are subject to local TN sales tax of 9.25%). Your annual membership won't officially begin until Grand Opening Day, so all of the climbing you get in before that is FREE! And who doesn't like free things?!

Don't you have a monthly payment option? Once we are fully open to the public, we will definitely be offering a monthly EFT payment option for membership. You can find out more information about our membership options here. However, to take advantage of the pre-opening period and get in to climb before grand opening day, you must purchase an annual membership.

How long will this pre-opening special be going on? Pre-opening memberships will be available for a limited time. When we get close to ending the sale, we'll be posting updates on Facebook. Let's just say...while supplies last. 

What's an "Onsight"?

“To me onsight climbing is the ultimate, the perfection; it’s putting it all together and making the best ascent you can on a route” - Lynn Hill

We are often asked by people unfamiliar with rock climbing what the word “onsight” means. We wanted to take a moment to explain the terminology and reasoning behind using it in the name of our climbing gym.

Onsight (noun or verb): A successful lead ascent of a climbing route on the first attempt, without falling or resting on the rope, and without any prior knowledge or specific information about the route.

An onsight is the purest form of ascent and the ultimate test of climbing mastery. A climber who is attempting to onsight a climb does not know where the difficult sections are or what moves might be used to get through them. The climber must rely solely on their own climbing skill, mental aptitude, and physical ability to climb the route while quickly solving difficult crux sections and intricate sequences as they arise. One wrong hold, a foot slip, or a mistake in a particular sequence could cost the climber the onsight.

In many ways, an onsight of a route translates well to the creation of Onsight Rock Gym. In a project of this magnitude, there are many unforeseen challenges and seemingly impossible cruxes to surmount along the way. The Onsight team will continue to meet and overcome each crux using our combined skills, mental perseverance, and unwavering determination. We will continue to push onward and upward to build the best climbing gym possible for the Knoxville community.
