Rainbow Ravine flows south from the Camels Hump Saddle for almost 1km when it joins Carmarthen Brook 250 metres lower.
Canyoners follow an established track up Rainbow Ravine from Carmarthen Brook to the Camels Hump and on across to Bells Line of Road.
This pretty ravine often has rainbows, hence the name.
Rainbow Ravine is well worth a visit even if you are not a canyoner.
