Aid climbing vs free climbing
In aid climbing, the climber uses technical tools to assist in climbing, whether it be bolts, trad climbing gear or aid climbing gear like hooks and aiders. Nowadays, this type of climbing is used very little. In earlier decades, big walls were usually only climbed technically, as they could not be climbed freely due to a lack of holds or the conditions in the wall being too difficult.
By the middle of the 20th century, people had reached the point where they could aid climb just about any wall if they had enough pitons. This was followed by the development of free climbing, which aimed to climb the desired wall/area using only the climbers’ hands and feet. This does not mean climbing without ropes or belay devices, in free climbing, these are still used for belaying, but progression is done mainly without the assistance of extra devices and tools. You do not load the belaying rope, pull on gear or use the rope for a sit down/rest. In the free climbing sector, there are different styles of climbing contained within the discipline, these are explained below. It is important to note that free climbing should not be confused and equated with Free Solo. Free Solo is an extreme form of free climbing, without the use of ropes, harnesses or other protective equipment.

Clean/Trad

In the clean/trad style, a route is climbed without fixed belay points. Pitons are not allowed. This means that the climber places all pieces of gear used as protection (and also to build an anchor if needed) and removes them completely after the ascent. In this case, the natural characteristics of the rock are used as placements for trad gear, like stoppers, cams or slings. Recognizing placements and correctly placing trad gear requires a lot of experience, which can only be acquired with a lot of practice. Clean/trad climbing follows the ethic of leaving no traces and especially not damaging the rock, and is practiced, for example, in the Elbsandsteingebirge (GER), on many granite walls in Chamonix (FR) and in Yosemite Valley (USA). Nowadays, there are also often routes that have bolted anchors, so the climber only has to place the intermediate protection.
In general, clean/trad can be defined more as a type of climbing than as a style of climbing, since a clean/trad route can be climbed onsight, flash, redpoint, pinkpoint, as well as on toprope. In the meantime, another climbing style has been established especially for clean/trad climbing, the so-called ‘greenpointing’ where a route is climbed clean/trad even though it is protected with bolts. But it only counts if you climb the route on lead. Now, you may ask yourself why you do that when there are bolts. However, there are many reasons for this. For example, there are climbers who simply like to fiddle around with friends and stoppers, or beginners who want to approach trad climbing slowly and would like to have bolts as a backup. In addition, there may be climbers who are in an area with routes far below their own difficulty level and where independently placing protection adds a certain pizzazz.
