The Khor Rori early South Arabian archaeological site, which has become a UNESCO site spread over a fairly wide area close to what once was an estuary. It is a restored fortified town, at the mouth of Wadi Darbat. Said to have been founded as an outpost and important harbour for the frankincense trade around the 1st century and eventually abandoned throughout the 7th century. Learning about the former transport and protecting strategies was quite interesting

A phenomenal archeological site displaying ruins from an ancient castle and town. Site remains are from 1 CE and more recent. Excellent site and purports to be the ancient site of Queen of Sheba's palace. The ruins are on a beautiful bay. We visited here in the peak of the heat, but it was not unbearable. A visitors center was in process of being built. Birding alert: there were numerous birds in and near the water below the ruins including flamingos.
