This is a spectacular route. Most people go to Tenerife and ride around El Teide volcano area. I did the same and for good reason. It is georgious there. It is easy to miss out on the northern part of the island because it is overshadowed by El Teide. Dont let this happen to you. The twisties are incredible in the northern part and the roads are very good. However, because of occasional rock slides you need to be alert to the possibilty of sand on the road which is almost nothing but corners. I have literally been all around the world I and I can say this is in the top 10, or maybe even 5, places I have seen. The scenery it well above par and the surface very nice.
