I flew from Tenerife North a few years ago, the name escapes me, its the one where the two 747s crashed on the runway. 2,000ft asl, very interesting weather there i must say. It was not expensive, certainly cheaper than home, went up with on of their instructors and circumnavigated the island of Tenerife, there's not much to see really, other than the Volcano it would be more interesting to go to the other islands and make a day out of it.
