Harimau Cave and Putri Cave Both caves lay in the same Padangbindu village 35 kilometers from Baturaja. Harimau (Tiger) Cave entrance is 40 to 50 meters wide and 20 to 35 meters height. Since 2008 to mid-2013 archaeologists have found 72 skeletons of mongoloid race with prediction 3,000 years of age and the excavation is still running. Some of the skeletons are displayed in Si Pahit Lidah (Bitter Tongue) Museum near Putri (Princess) Cave. Putri Cave has 20x160 meter square pond.
Harimau Cave is located 30 meters above Air Kaman Basa River and 1.5 kilometers from Ogan River. Archeologists estimate that the cave has been used for 15 millennia, with traces of three different cultures, the latest being 3,500 years ago (Bronze Age) with metal tools similar to those found in Dong son sites (Vietnam). There are also 34 geometric pictures in Harimau Cave which the picture is never found at any other caves in Sumatra. On March 14, 2015, after midnight, a big flood which never occurred before appeared ruins tourist facilities inside the cave and also the facilities in the ground in front of the cave; tourism facilities are predicted 70 percent damaged, but the condition of the pictures are not yet announced.
