geocaching

I hadn't heard of that, bit like Dartmoor letterboxing

Yes, very much so. It's fun. You can do it with any GPS equipment where you
can input a gps co-ordinate. You have to work out the clues a start point
which gives you the next co-ordinate, where you can find the next clue...
and so on. Sometimes only one step, sometimes more.
