On the web I came across this highly experienced and professional tour agent, DesertSoul .
They offer amazing trips in Morroco, Tunisia, but also Bosnia. They advice taking the longer 8, 11 or 12 day trips, to enjoy the full monty.
Also for 4×4 trips, MTB and even running trips, they organise it all….
