Lan Hin Taek, the rock field with an area of 40 rai (around 15.8 acres ). Lan Hin Taek is one of the two fissures in the park which is believed to have come from the shifting of the Earth’s crust. Some crevices are narrow enough to jump across, others are wider. This rock field is blanketed with plant species such as mosses, lichens, ferns, wolf’s claws and orchids which grow in rock crevices.
