The group organiser, Dr Olver, found the tour driver you contracted for their tour most knowledgeable. He had a real interest in geology and volcanoes and was extremely helpful. When this group repeats the tour in 2016 he is hoping to have the same driver so do please keep note of his name! I understand that they just made it across the F26 road before the weather changed and that even one day later would have made the journey too risky. Apparently they found a very poorly equipped German cyclist on the road with inadequate clothing and no idea where he was going so they loaded him on to the coach and took him to safety!
