Qatar Nerampokk on Instagram: "Dahl Al Misfir Cave, located near Rawdat Rashed in Qatar, is one of the country’s most unique natural formations. It’s a deep sinkhole cave known for its layers of gypsum crystals, which can emit a faint glow deep inside the cave under certain conditions hence the name “Cave of Light.” The cave is estimated to be around 40 meters deep . #DahlAlMisfir #DahlAlMisfirCave #CaveOfLight #ExploreQatar #VisitQatar #QatarNature #HiddenQatar #QatarLandmarks #QatarTravel #Qat
