These are becoming increasingly important tourist attractions and are important for serious cavers.
The caver's primary light source is usually mounted on the helmet in order to keep the hands free.
Further passage takes the caver downwards towards the canyon.
Knee pads, and less commonly, elbow pads are worn both to protect the caver and the caver's clothing.
The cavern was the site of a fatal accident in 1960, when a young caver was hit by rock-fall.
However, capping requires the caver to manually strike the firing pin which may result in injury.
The cave continues beyond, and is open to the experienced caver.
Livesey was not only a top rock climber but also a fell-runner, athlete, caver, canoeist and orienteer.
