Solo climbing, or soloing, is a style of climbing in which the climber climbs a route alone, without the assistance of a belayer (or "second"). By its very nature, it presents a higher degree of risk to the climber, and in some cases, is considered extremely high risk (e.g. solo ice climbing, or solo big wall climbing). Note that the use of the term "solo climbing" is generally separate from the action of bouldering, which is itself a form of solo climbing, but with less serious consequences in the case of a fall. The most dangerous form of solo climbing is free solo climbing, which means both climbing alone and without any form of climbing protection.^[1]

Minimal protection

The following types of "solo climbing" have minimal or no form of climbing protection, and the climber exposes themselves to potentially fatal risks in the event of a fall:^[2]

• Free solo climbing (sometimes referred to as soloing in the UK, or third-classing in the US)^[2] is where the climber uses no climbing protection (or any form of climbing aid, except for their climbing shoes and their climbing chalk), and ascends a single-pitch, or a multi-pitch/big wall climbing route.^[2]

Free soloing is the most dramatic solo technique, and in 2017 became an Oscar-winning documentary film, Free Solo that featured Alex Honnold free soloing the 915-metre (3,002 ft) 35-pitch rock climbing route Freerider in Yosemite, the world's first-ever free solo of a 5.13a (7c+) big wall route in history.^[3][4]

• Deep-water soloing (DWS), is a subtype of free solo climbing performed on rock faces that overhang above water where in the case of a fall, the climber lands in the water.^[2] Extreme deep-water solo routes have falls of over 20–40 metres (66–131 ft), and thus a risk of serious injury.^[2] Noted DWS climbers include Chris Sharma who created the world's first-ever 9a+ (5.15a) DWS route, Es Pontàs, in 2007.^[5]
• FreeBASEing, is a subtype of free solo climbing performed on long multi-pitch big wall routes with a BASE jumping parachute as the sole means of protection, where a falling climber opens their parachute to arrest their fall.^[2] FreeBASEing was pioneered by Dean Potter who made a freeBASE ascent of Deep Blue Sea (5.12+) on the north face of the Eiger in 2008.^[6][7]
• Highball bouldering, is where the boulder exceeds 7–10 metres (23–33 ft) in height, and therefore any fall, even where bouldering mats are used, presents a risk of serious injury.^[2] Where highball bouldering ends and free soloing begins is a source of debate amongst climbers.^[8] Notable highball boulders include Nalle Hukkataival's Livin' Large V16 (8C+) in Rocklands, South Africa.,^[9] and Ron Fawcett's Careless Torque 8A (V11) in Stanage Edge, England.^[10]
• Free solo ice climbing can also be done in a free solo format (e.g. without any protection, such as ice screws). Notable free solo ice climbers include Canadian Marc-Andre Leclerc,^[11] and Swiss ice climber, Dani Arnold, who has free soloed routes of grade WI7.^[12] Related to this is the activity of mixed climbing free soloing (e.g. using ice climbing equipment on routes that are a combination of ice and rock).
• Buildering, is a subtype of free solo climbing where the climber ascends a public building (or mechanical structure with crane climbing), and usually without any protection.^[2] Notable building climbers include Alain Robert (who also made world's first-ever free solo of an 8b (5.13d) climbing route), who has free soloed major buildings including the Eiffel Tower and the Burj Khalifa.^[13]

Full protection

The following types of "solo climbing" have a form of climbing protection, which typically involves a mechanical self-locking (or progress capture/assisted braking) device that significantly reduces the risk of serious or fatal injury to the climber:^[2]

• Rope solo climbing is climbing alone but with a rope to help arrest a fall, or for a self-rescue if required.^[2][14] Instead of having a belayer, the climber uses a self-locking device that will hold the rope in the case of a fall, and leads the route in a traditional climbing manner, placing climbing protection as they ascend. One end of the rope is anchored below the climber and the climber pays-out the rope through the self-locking device as they ascend. Once they reach the top, they need to abseil down and re-ascend the route with an ascender, to remove the protection they placed earlier.^[15]

In 1992, French climber Catherine Destivelle used a self-locking device to rope-solo the first part of the traditional climbing route El Matador 5.10d (6b+), on the Devils Tower in Wyoming (she free soloed the second part), and was captured in the climbing film, Ballade à Devil's Tower.^[16] In 1992, Destivelle used rope solo technique to create Voie Destivelle (VI 5.11b A5) on the west face of the Petit Dru, and was captured in the climbing film, 11 Days on the Dru.^[17] In 2016, Pete Whittaker rope-soloed the 915-metre (3,002 ft) 35-pitch route Freerider in Yosemite in a single day.^[15]

• Top rope solo climbing is a form of top roping where a single static fixed rope, anchored to the top of the route, is laid along the length of the climb. The climber then clips-into the fixed rope using at least one progress capture device (PCD) such as a Petzl Micro Traxion or a Camp Lift, that will allow the rope to pay-through as the climber ascends but will grip the rope tightly in the event of a fall.^[18][19]
• Auto belay indoor climbing is usually a form of top roping (although there are lead auto belay devices) where the belayer is replaced by a mechanical device permanently fixed the top (or bottom for lead auto belay) of the route.^[20]

In film

A number of notable films have been made focused on solo (and free solo) climbing (on rock and/or on ice) including:^[21]

• The Alpinist, a 2021 documentary film about Canadian alpinist Marc-André Leclerc, with solo, and free solo, of rock, ice, and alpine routes.
• Free Solo, a 2018 Netflix documentary film about Alex Honnold's free solo climb of Freerider 5.13a (7c+) on El Capitan.
• King Lines, a 2007 documentary film about Chris Sharma, featuring his free solo climb of the DWS route, Es Pontàs 9a+ (5.15a), in Mallorca.
