Its was raining heavily that day, the tour guide should have call off the hike because the rain that give rise to rapids waterfall and gushing waters stream along the hiking route. It is life-threatening conditions hike because of the rain conditions, why the guide did not call it off I did not know?
The tour details did not specific need hiking shoes and water proof jacket and operate in all weather conditions when I booked the tour weeks ago. But they change it on the website when I re-visited today.
Any way, it is important to consider the life risking hiking conditions caused to hikers during raining conditions!
