About 35 metres below Guthole (Guzzle Hole) on the right side of the flood channel. Access is only possible in dry weather.
Description
A short drop down to the side of the flood channel leads to a spacious river passage. Upstream leads to a deep sump after 12 metres and downstream leads to a series of wide ducks after 20 metres. Beyond the ducks, the passage branches into two which meet again just before the terminal deep sump.
