Marhaba is the taxi service provider in Oman and have its own mobile application. They are only allowed to pick up passengers from the airport and most hotels, and they only operate within Muscat.

Oman’s orange and white privately owned taxis are typically found along the main roads of every city and major town, but be warned they are not fitted with meters so you should agree on the fare with the driver before you start your journey. Alternatively consult the fare on their respective mobile application. 

Car rentals in Oman are reasonably affordable and their services are available everywhere, including airports. Keep in mind that you do need a driver’s licence (issued from your home country) and cars are driven on the right-hand side, meaning you overtake on the left.
