I am planning a holiday in Tenerife later this year and I would like to do some cycling. I can cycle but I would like to improve my confidence and ability in a relatively safe environment.
Great! What would you like to know?
Tenerife is a safe enough place for cycling regarding other road traffic… nevertheless, there are certain roads to avoid because of high levels of traffic or poor quality road surfaces. Quieter mountain roads are better than coastal routes.
Also, most accidents we have seen are due to rider error (going down around corners too fast and mixing up front/rear brakes for example). Tenerife is also not the best place to learn with clipless pedals due to the abundance of hill starts. The flattest road for beginner cyclists is between Granadilla de Abona and Güímar which undulates along road TF28.
Hope this is of some help.
