There are several hire car outlets in Birkat Al Mawz, but this family-run company has a very good reputation, and the owner has extended his operation over the years into a full tour service. A 4WD (mandatory for the ascent to Jebel Akhdar) costs OR35 for 24 hours. Saloon cars are available from OR10.
Overnight half-board camping trips to Jebel Akhdar for a minimum group of four cost OR25 per person (or OR50 for one night and two full days). A guided tour through Birkat Al Mawz, visiting the falaj (irrigation channels), plantations and old houses is worth enquiring about.
