Exertion and Skill Level

Indoor climbing nights are fit for everyone! Exertion levels may range from light to vigorous depending on the experience you are seeking, your physical activity level, and your experience with climbing. There are plenty of routes to choose from with a variety of difficulties at all the gyms we partner with. Every indoor climbing night will offer an optional orientation class for those who have never climbed or belayed before (details below). 

Climbing, Belaying and Bouldering

Climbing vs. Bouldering: What's the difference?

Climbing is often a two-person sport – one person climbs and one person belays. The belayer is the person on the ground who is maintaining tension on the ropes for the climber, so the climber will not fall even if they lose their grip on the rock/wall. Some gyms also have auto-belays, a machine that lowers the climber automatically at a slow and controlled rate, so you don’t need a belay person on the ground.

Bouldering is done by one person without ropes on walls up to 15’ with big cushions underneath.

Climbing on belay and bouldering are both available at any indoor gym we will go to. The gym is wide open, so you can switch between the different areas as you choose!

Belay Class Required or not?

In order to belay at any gym, you will need to pass a belay test at that gym. We want everyone to learn how to belay, so if you never have belayed or it has been a long time and you need a refresher, please register at least a week in advance and choose "Belay Course Requested" so that we can get you on the list. If there is no space remaining in the belay class on the night for which you are registering, don't worry - you can still climb (while being belayed by an approved belayer), use the auto-belays, and/or use the bouldering walls!

If you already know how to belay, including forming a proper double figure-eight knot with backup and the PBUS belay method (Pull, Brake, Under, Slide), you can take the test upon arrival and if you pass, you will be allowed to belay others immediately. When you register, you can choose "No Belay Class."
