Bukit Jernih (GPS: 6.51907, 100.26283) is the name of the twin limestone outcrops in Perlis. It is located in Bukit Ketri, near the Bukit Ketri Railway Station. The karst outcrops have sheer cliffs that rise almost vertically. These cliffs are punctuated by caverns and caves at the base. These twin peaks are a local landmark. They are particularly beautiful on a day with clear sky.
