Some suggestions to see would be:
Khor Rori and while you're out there you could experiment on the magnetic road where cars seem to roll uphill backwards.
The maritime museum and Al Baleed
The Prophet Job's tomb
The blowholes at Al Mughsayl
The tomb of Umran (its about 30ft long) and close by is a building containing a rock with a hoof print of the Prophet Saleh's camel.
Hello! Am visiting Salalah in October for 3 days. Grateful if you can advise whether we need to hire a car for a day or two and which are the must-see places we should visit? Also, restaurant and souks would be appreciated too!
TIA.
