Qaal'at Al Muwayh al Qadim, otherwise known as the King Abdulaziz hunting lodge, is concealed behind a low ridge of hills and is alongside a salt plain which is itself bordered by one of the many lava flows in the area. The hunting lodge itself was originally a black lava stone caravanserai situated on Darb al Hejaz, the old caravan route from Riyadh to Taif. Later converted to its most recent use as a hunting lodge by King Abdul Aziz it is now abandoned as is the old village of Muwayh beside it.
