Your jeep is hooked up by radio to a lead, trailblazer jeep that shows the way and sets the pace. When you come to a river or other obstacle, the convoy stops and you get expert instruction from the guide in the lead jeep on how to proceed. You also stop at points of particular interest along the way and do a bit of camping and have a few invigorating walks and maybe even a swim in a geothermal river. On the road,your guide will not only give you instructions by radio but will also impart local lore and historical tidbits as you proceed. There are two itineraries - a two day one for the stopover set and a five day one for those who want a longer, more ambitious ride.
Most tours are in English, but arrangements for other languages can be made.
Given that everything is included, it doesn't cost the earth, but since price depends on time of year, type of jeep and number of persons in your party, you'll have to E-mail the company for specific prices and booking information.
