What Does ‘Flash’ Mean?

It’s impossible to flash every route or boulder, but when you do, it’s such a great feeling. Make sure you check out our guide if you want to flash like Adam Ondra.

Lead vs Toprope: What’s the difference?

Toprope is your introduction into climbing. Lead climbing is where the real stuff happens. But what is the difference?

Rock climbing is a sport filled with its own unique language, a collection of terms, slang, and jargon that can seem like a foreign language to the newbies. Not to mention all the strange climbing techniques climbers use (why is that climber hanging like a bat?!)

Whether you’re a seasoned climber or new to the vertical world, understanding climbing terminology and techniques can enhance your experience and help you connect with the climbing community. 

Below is an alphabetical compilation of rock climbing terms and techniques to get you from newbie level to pro. 

I have listed every term and technique under the sun, but if I have missed anything, give us as a shout in the comments box below or get in touch with us here!

Climbing Terminology & Techniques From A-Z


  • Abseil (Rappel): The process of descending a rock face using a rope.

  • Approach: The path or route taken to reach the base of a climb.
  • Arete: A sharp ridge formed by two intersecting planes of rock.
  • Armbar: A technique where climbers use their arm to press between two rock surfaces for stability.
