The Mir Tours Staff have been engaged in this hobby for some time. Geocaching is a "treasure hunt" with a gps unit and the aim is to find the hiding place and log in.
This can be done nearly everywhere, you do not need much to do it. Ideally you get to go out and about, see new places and meet interesting people.
There area various forms of hiding places log containers and ideas making ita lot of fun.
This programme is suitable for starters as well as the more advanced. Anyone not interested in the geocaching may partake in the programme just as well.
