This fascinating park is part museum and part archaeological site and you can wander around the ruins and watch the archaeologists at work. Visit the gallery within the site to see some of the 1st century BC to 3rd century AD finds from the site including some evocative Kursi inscriptions. There are toilets but no other facilities here.
Khor Rori is about 35km east of Salalah. Take the Mirbat road and follow the brown signs. A microbus to the junction on the highway is 500 baisa. A new amphitheatre may soon offer a sound-and light-experience.
