Camel ride in the Sahara Desert.
Sounded like a good idea at the time we booked the tour and to be honest I am glad I experienced it but a shorter ride would have been better.
We rode for over an hour in the evening, had dinner and camped in a very cold tent, and then rode back to the buses in the morning. This was part of a budget tour and you pretty much get what you pay for, even less in Morocco.
