These tours can be for 2, 3, 4, or 5 hours. The longer tours are able to visit more locations and reach further into the desert.
A 5 hour tour would include:
Wadi Rum Village - Lawrence Spring - Red Sand Dune - Khazali Canyon - Small Rock Bridge - Lawrence House - Um Frouth Bridge - Abu Khasabha Canyon – Burdah Rock Bridge
Whether you can see all of these places depends on which tour you choose! Shorter tours are able to visit some of these locations, but not all.
