What goes up must come down. You may be aware that down climbing is much more difficult and time consuming than climbing upwards, as well as sounding a little contradictory. This is because it's much harder to see where the holds are when they're below you. It might also have something to do with the mental challenge of constantly looking down at the yawning abyss below...

However, surely gravity is on your side here? There must be an easy way down. Well, there is – the rappel! This is why rappelling is such a widely used technique in rock climbing. But what is rappelling and is it as scary and dangerous as it looks?

We asked one of our climbing experts to explore the rappel, taking a look at its history, how to do it, the equipment you'll need and how to make sure you do it safely.

What is rappelling?

Rappelling is the climbing term used to describe the act of descending a mountain, crag or wall on a rope that is attached to an anchor at the top. It's more commonly referred to as abseiling in some countries. 

It is a climbing technique used to get down in a timely and efficient manner, as opposed to having to climb back down.

Rappelling is most often employed as the descent after an upward climb, however it has become something of an adventure sport in itself these days. Rappelling can also be used as a means of lowering into a slot canyon or for spelunking, and is even used by the military to access hard to reach locales.

Origins of rappelling

Many attribute its invention to Jean Charlet-Straton who reportedly devised it after getting stuck descending Le Petit Dru in the French Alps in 1876. However, the Alpinist claims that at that time Edward Whymper, best known for the first ascent of the Matterhorn at the end of the Golden Age of Alpinism, had already been using the technique.

Regardless of who first conceived of the idea, it was a good one. Charlet-Straton spent several more years perfecting the technique and it quickly caught on among the climbing community as the best way to descend.

How do you rappel?

First and foremost, rappelling is inherently dangerous and it is something you need to learn in person from a trained professional, and not from the internet. It usually involves two ropes and two people (though you can self-rappel using only one rope) and therefore the margin of error is high and mistakes can be deadly.

The basic idea is that the ropes are passed through the top anchor and through the belay devices attached to your harness and your partner’s harness. Typically, from the top of a climbing route you will remain facing the rock and lean back while your partner on the ground below slowly feeds the rope through their belay device to lower you smoothly down.

Depending on the grade of the cliff, you might need to use your feet to push off the rock like you’re taking long, slow jumps, or if not possible you will be suspended in the air for the descent and just use your hands. This is known as free rappelling. At the bottom you should land lightly on your feet.

Though these tips are not intended to be a replacement for proper training, there are a few things you can do every time to lower your risk of a rappelling accident. 

  • Tie knots at the ends of your ropes so you don’t slide off the end
  • Tie an additional knot as a brake, known as a prussik knot, or use an auto locking belay device  
  • Make sure you have a climbing partner who you trust and that neither of you is distracted when tying off your belay devices  
  • Communicate with your climbing partner
