We had planned to visit some of the sights in Valencia, Negros Oriental that day. We drove from Dauin to the town of Dumaguete to run a few errands. Then we took one of the roads uphill from the city to Valencia. It’s really not that far, but Valencia is a big city.
Among the sights for the day were the sulphur chimneys. It is a remarkable experience to drive through and, above all, over these chimneys. The boiling water not only seeps out of the ground on both sides of the road, but also in small holes in the middle of the road.
On arrival, the surprised visitor is immediately hit by the stench of rotten eggs, which lingers for quite a while.
It is an impressive sight to see this force of nature.
The unpleasant smell of rotten eggs in the sulphur vents at Palinpinon is due to the presence of hydrogen sulphide (H2S), which is released along with steam and other gases when the groundwater is heated by underlying rock and brought to the boil.
