Agop Batu Tulug is a steep limestone cliff that stands 39 meters high and is part of the 20-25 million- year old Labang limestone formation. The word ‘agop’ in the Orang Sungai language means cave. There are three main caves, agop suriba (lower) on the forest floor, lintaga (middle) and sawat (upper) betweeen 12-15m high.
Inside the middle and upper caves are more than a hundred carved wooden coffins dating back 200-250 years, watched over by bats and swallows. Batu Putih village can be viewed from here as well.
The coffins resemble different animals associated to the beliefs of the Orang Sungai but it has also been said that they are the coffins of the Chinese who once settled in the area as Chinese artifacts were found among the remains.
A site Museum since 1996, it has facilities such as an information center, stairs leading to the caves, toilets and resting huts.
