Salalah is the capital of Oman's southernmost Dhofar region. It is often considered to be the "second city" of the Sultanate, although some of this designation is probably due to its distinction as Sultan Qaboos' birthplace.
The Dhofar region is famous for its khareef (monsoon), and the Khareef Festival is an annual event here. Many locals will in fact be quite surprised to see non-Arab visitors at other times of year.
